An asymmetric monoborylation of alkenylsilanes catalyzed by a copper(I) complex with the chiral bisphosphine ligand BenzP* is reported. The reaction proceeded with excellent regioselectivity and high enantioselectivity to afford the corresponding opticall

(Diiodomethyl)trimethylsilane (Me3SiCHI2, 1) is produced by treatment of iodoform with manganese in the presence of Me 3SiCl. Aldehydes are converted to (E)-1-trimethylsilyl-1-alkenes in a stereoselective manner with a geminal dichromium reagent generated from 1, manganese, Me3SiCl, and a catalytic amount of CrCl 3[thf]3 in THF. Similarly, (E)-1-alkenylboronic esters are prepared stereoselectively in good to excellent yields by treatment of aldehydes with a geminal dichromium reagent derived from Cl2CHB(OR) 2 [(OR)2 = OCMe2CMe2O] and LiI instead of 1.
Highly Stereoselective Synthesis of Vinylsilanes from Carbonyl Compounds

The in situ generated (chlorolithiomethyl)trimethylsilane reacts at -60 deg C to -45 deg C with different aldehydes or ketones 1 to afford, after lithation with lithium naphthalenide at -78 deg C to 20 deg C, vinylsilanes 5a-h in a stereoselective manner.
