The recently found (1) stereospecific transformation of benzaldehyde by the reagents Ph3M-CH(I)Li (M= Si, Ge) to Ph3M-substituted oxiranes renders possible a method for olefination of benzaldehyde to give Z- or E-olefins, alternatively.This is demonstrated with two examples. - The synthesis of Ph3Sn-CH(I)Li is described.
