Twonew Rh(I)-catalyzed methods for the synthesis of chiral alpha-branched amines via addition of arylboronic acids to N-tert-butanesulfinyl and N-diphenylphosphinoyl imines have been developed. The syntheses are more functional group tolerant than alternative methods utilizing Grignard or organolithium reagents, and the imine activating groups used are easily removed. These methods are both high-yielding

imine derivatives with functionalized aryl pronucleophiles is reported. The aryl nucleophiles are released from silicon-protected aryl-substituted diazenes by desilylation with potassium trimethylsilanolate concomitant with the loss of dinitrogen. A broad range of functional groups is tolerated in the aryl nucleophile but, depending upon their electronic effect, require specific groups at the imine
