Reaction of C-silyl-P-chloro-alkylidenephosphoranes with carbonyl compounds

Reaction of P-chloroylides with carbonyl compounds leads to the formation of four-membered phosphorus heterocycles - 25-chloro-2,2-oxaphosphetanes. The 2-chloro-2,2-oxaphosphetanes depending on substituent R at α;-atom carbon, rearrange with formation of 2-chloroalkylphosphonates (R = H, Alk, Ar) or with elimination of trimethylchlorosilane (R = Me3Si) convert into trans-phosphorylated alkenes.

Copper-mediated cross-coupling of 1,1-dibromo-1-alkenes with dialkyl phosphites: A convenient synthesis of 1-alkenylphosphonates

An efficient and stereoselective procedure for the preparation of E-1-alkenylphosphonates by copper-mediated cross-coupling between 1,1-dibromo-1-alkenes and dialkyl phosphites is reported. The reaction allows for formal substitution of both bromine atoms
