The authors report on three Indo-Pacific opisthobranch species found during scuba diving along the south western coast of Turkey in Kas area. One species, a nudibranch Spurilla major is a new ...addition to the alien marine fauna in the Mediterranean Sea, while sacoglossan slug Oxynoe viridis and nudibranch Flabellina rubrolineata have already been found in that area. However, O. viridis has not yet been included in the CIESM Atlas of Exotic Molluscs. We also report on the first record of Atlantic subtropical mollusc species, Chelidonura africana and a circumtropical species of a sea hare, Aplysia dactylomela found in the aquatory of the Island of Susac in the Southern Adriatic Sea, Croatia. Finally, we report on an unusual aggregation of a well established lessepsian migrant Bursatella leachii in Strunjan salterns, Slovenia.Original Abstract: Gli autori riportano la presenza di tre specie indo-pacifiche di opistobranchi, avvistate durante immersioni lungo la costa sud occidentale della Turchia, nell'area di Kas. Una specie di nudibranchi, Spurilla major, viene cosi ad aggiungersi alla lista della fauna marina aliena del mare Mediterraneo, mentre il sacoglosso Oxynoe viridis ed il nudibranco Flabellina rubrolineata erano gia stati segnalati per quest'area. In ogni caso, la specie O. viridis non e stata ancora inserita nell'Atlante dei Molluschi Esotici della CIESM. L'articolo segnala pure il primo ritrovamento di una specie subtropicale atlantica, Chelidonura africana, e di una specie circumtropicale di anaspidei, Aplysia dactylomela, segnalate per le acque dell'isola di Susac, nell'Adriatico meridionale, in Croazia. Gli autori infine discutono l'inusuale aggregazione dell'immigrante lessepsiana Bursatella leachii, ben stabilita nelle saline di Strugnano, in Slovenia. Avtor poroca o treh indo-pacifiskih vrstah zaskrgarjev, najdenih med potapljanjem ob jugozahodni obali Turcije, v predelu Kas. Ena od vrst, goloskrgar Spurilla major, predstavlja novo tujerodno morsko vrsto v Sredozemskem morju, medtem ko sta bila zeleni strgalec Oxynoe viridis in goloskrgar Flabellina rubrolineata ze opazena na tem obmocju, ceprav zeleni strgalec Oxynoe viridis se ni vpisan v CIESM Atlas eksoticnih vrst mehkuzcev. Clanek posreduje tudi prve podatke o atlantski subtropski vrsti mehkuzca Chelidonura africana in pegastem morskem zajcku Aplysia dactylomela, najdenih v akvatoriju otoka Susca v juznem jadranskem morju, Hrvaska. Porocilo vsebuje tudi opis nenavadne zdruzbe ze uveljavljene lesepske selivke Bursatella leachii v Strunjanskih solinah, Slovenija.
Kinetics and product analysis of detritylation of N-tritylamlodipine by benzenesulfonic acid in methanol, methanol-chloroform (volume ratio 9:1), ethanol, 2-propanol, and methanol/2-propanol (mole ...ratio 1:1) have been investigated by HPLC; amongst these reaction conditions are ones closely similar to those of one method of manufacturing amlodipine benzenesulfonate. Kinetics of detritylation of Ntritylamlodipine have also been investigated in methanol-d^sub 4^ by ^sup 1^H NMR spectroscopy and the agreement with the results by HPLC is good. The rate of detritylation increases with increasing concentrations of benzenesulfonic acid, and p-methoxy-substituents in the trityl group have been shown to lead to faster reactions. In methanol, the rate is hardly affected by 10 % (vol. fraction) chloroform. These studies relate to mechanistic investigations of acid-catalysed deaminations of methoxy-substituted tritylalkylamines, and Arrhenius activation parameters (E^sub a^ and A) are similar indicating a common generic mechanism. Acid- catalysed trans-esterification has been shown by HPLC to accompany detritylation in methanol, and attendant protium-deuterium exchange in the methyl at C6 by reversible acid-catalysed iminium ion formation in the 4-aryl-1,4-dihydropyridine moiety of both N-tritylamlodipine and amlodipine has been investigated in deuteriated methanol by ^sup 1^H, ^sup 13^C, and ^sup 15^N NMR spectroscopy. PUBLICATION ABSTRACT
A less known decapod species Herbstia condyliata (Fabricius, 1787) has been recorded for the very first time in waters off the Slovenian coast, which is the northernmost locality for this species in ...the Adriatic Sea. The species is considered rare in the eastern Mediterranean; however, it is apparently common in the Adriatic Sea, where it is distributed from southern Dalmatia to the Gulf of Trieste.Original Abstract: Una specie meno nota di crostacei decapodi, Herbstia condyliata (Fabricius, 1787), e stata trovata per la prima volta nelle acque al largo della costa Slovena, il che corrisponde alla localita piu settentrionale per questa specie nel mare Adriatico. La specie e considerata rara nel Mediterraneo orientale, per quanto la sua presenza risulti apparentemente comune nel mare Adriatico, dove la si trova dalla Dalmazia meridionale al Golfo di Trieste. Manj znana rakovica Herbstia condyliata je bila prvic zabelezena v slovenskem delu Jadranskega morja, kar je obenem tudi njena najsevernejsa lokaliteta v Jadranskem morju. Ceprav naj bi bila ta vrsta redka v vzhodnem Sredozemlju, kaze, da je Jadranskem morju razmeroma obicajna in jo najdemo od juzne Dalmacije pa vse do Trzaskega zaliva.

Kinetics of detritylation of Ntritylamlodipine have also been investigated in methanol-d4 by 1H NMR spectroscopy and the agreement with the results by HPLC is good. The rate of detritylation increases with increasing concentrations of benzenesulfonic acid, and p-methoxy-substituents in the trityl group have been shown to lead to faster reactions. In methanol, the rate is hardly affected by 10 % (vol. fraction) chloroform.
