- 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 selective cross-coupling of 1,1-dibromo-1-alkenes and heteronucleophiles: Development of general routes to heterosubstituted alkynes and alkenes
-
Efficient and general procedures for the cross-coupling of 1,1-dibromoalkenes and N-, O-, and P-nucleophiles are reported. Fine-tuning of the reaction conditions allows for either site-selective, double, or alkynylative cross-coupling, therefore providing

-
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
