Reaction of tricoordinated phosphorus compounds with heteroatomic oxidizing agents

Reaction of tricoordinated phosphorus compounds with heteroatomic oxidizing agents 

In the direct synthesis of thiophosphonium salts, the oxidizing agent can be a disulphide using either constant-current electrolysis (c.c.e) conditions or by simple addition with benzoic acid433 (reaction 122). 

By constant-current electrolysis of triphenylphosphine with alcohol and benzoic or succinic acid the alkoxyphosphonium perchlorates can be obtained434 (reaction 123).
