Abstract: The reaction of 2,4-bis(phenyl)-1,3-diselenadiphosphetane-2,4- diselenide (Woollins' Reagent, WR) with phenylalkyl-cyanamides (RR'NC N, R = PhCH2CH2, R' = CH3 and R = PhCH2CH2CH2, R' = H) in refluxing toluene led to novel heterocyclic selenazadiphospholaminediselenides 1 and 2 (43% and 42% yields), the latter being hydrolyzed to the unusual zwitterionic carbamidoyl(phenyl) phosphinodiselenoic acids 3 and 4 in excellent yields (96% and 98%).
