The first step of hydrolysis of compounds 1 , 2 and 4 involves the protonation of the PN nitrogen atom. 3 does not react with water in the absence of a catalyst. Protonation of compounds 1 – 3 by a strong acid such as CF3SO3H is studied by 15N a

Cycloaddition of dichlorophenylphosphine with 3,4-bis(methylene)-thiolane affords a bicyclic phospholenium salt; further reactions with water and dihydrogen sulfide give new series of bicyclic phospholenes.

So far organophosphorus chemists have been interested in synthesizing low coordinated phosphorus compounds and in studying them in solution at temperatures rarely above 300 °C. As a matter of fact there are few reports on the behaviour of dicoordina
