摘要
Palladium catalyzed hydrogenolysis of 1,1-dibromo-1-alkenes by tributyltin hydride proceeds smoothly to give (Z)-1-bromo-1-alkenes with excellent stereoselectivity in good yields. Dibromomethylenation of aldehydes by a combination of CBr4 and Ph(3)P in methylene chloride and the successive hydrogenolysis affords (Z)-1-bromo-1-alkenes in one-pot.
