The O-silylated dienolates of α,β-unsaturated ketones and aldehydes can be thiophosphorylated using O,O-dialkylchlorothiophosphonates and O,O-dialkylbromodithiophosphonates to give a new class of compounds thio- and dithiophosphates 1-4 in high yield.

Synthesis of (z)-1,2-diheterosubstituted-1,3-dienes. novel annelating agents
Readily available thiophosphates containing an alpha,beta-unsaturated moiety have been efficiently converted into the novel (Z)-1,2-diheterosubstituted-1,3-dienes by treatment with sodium hydride followed by the corresponding electrophile
