An efficient, two-step synthesis of alpha-phosphorylvinyl selenides 4 from a-phosphoryl sulfoxides 1 is described which involves selenenylation reaction and subsequent thermal sulfoxide elimination. Oxidation of 4 leads to alpha-phosphorylvinyl seienoxides 5 which upon thermoiysis afford alkynylphosphonates 6.
