photoinduced reactions of tetraphenyldiphosphine disulfide
with a range of organic dichalcogenides successfully afforded a series
of phosphorus(V)–chalcogen interelement compounds via a radical
process. The relative reactivities of the organic dichalcogenides
(i.e., (PhS)2, (PhSe)2, and (PhTe)2) toward the PIII or PV groups in the diphosphine
analogues under light were investigated in detail, and a convenient
method was developed to form P–S or P–Se interelement
compounds from tetraphenyldiphosphine disulfide and (PhS)2 or (PhSe)2 upon photoirradiation. Furthermore,
the relative photochemical properties and reactivities of tetraphenyldiphophine
(P–P interelement compound) and its analogues toward photoinduced
radical addition reactions were also discussed. The formed P–E
(E = S, Se) interelement compounds could be utilized for ionic reactions,
and they could be transformed into various phosphine reagents via
one-pot processes.
