Abstract
A mixture of trans-[M(N-2)(2)(dppe)(2)] (M = Mo or W; dppe = Ph2PCH2CH2PPh2 ) and dppe was heated to reflux in benzene or toluene to give the M(0) comp lex [M(P-4)(dppe)], which contains the novel tetradentate phosphine o-C6H4 (PPhCH2CH2PPh2)(2) (P-4) arising from the coupling of two dppe ligands. The reaction of [Mo(P-4)(dppe)] with CO afforded the carbonyl complex [Mo(CO)( 2)(P-4)].
