A new method involving mild acryl transient-chelating-group-controlled stereoselective Rh( i )-catalyzed silylative aminocarbonylation of 2-alkynylanilines with CO and silanes is presented for producing ( Z )-3-(silylmethylene)indolin-2-ones. Upon using an acryl transient chelating group, 2-alkynylanilines undergo an unprecedented alkyne cis -silylrhodation followed by aminocarbonylation to assemble ( Z )-3-(silylmethylene)indolin-2-ones. Mechanistic studies show that acryl transient chelating effects result in the key alkyne cis -silylrhodation process. Transient-chelating-group-controlled stereoselective rhodium(I)-catalyzed silylative aminocarbonylation of 2- alkynylanilines with CO and silanes toward (Z)-3-(silylmethylene)indolin-2-ones is presented.
