Abstract

Organo-phosphorus compounds S 0080Efficient Generation of Phosphorus-Carbon Bonds via a Rearrangement of P(III) Esters Catalyzed by Trimethylhalosilanes. -Generally, the phosphorus esters rearrange in the presence of catalytic amounts of Me3SiX (X=Br, I) into the corresponding phosphoryl systems (reaction mechanism). When esters (X) or (XII) and halotrimethylsilanes are used in a 2:1 ratio, phosphonium salts are formed as major products. -(DABKOWSKI*, W.; OZAREK, A.; OLEJNICZAK, S.; CYPRYK, M.; CHOJNOWSKI, J.; MICHALSKI, J.; Chem.
