✦ Synopsis
The coordination chemistry of secondary phosphine oxides has recently been reviewed [2]. The knowledge of the behaviour of secondary phosphine sulfides and selenides towards transition metal complexes is essentially confined to carbonyl systems of group VI and VII metals to data [3] . Marsala, Faraone and Piraino [4] have recently shown that Ph,P(S)H reacts with the da complex Ir(CO)(PPh&Cl to form Ir(CO)H(PPh,)a(SPPha)Cl containing a S-linked thiophosphinito group. In the case of Rh(CO)(PPh,)Cl the oxidative addition reaction forming a rhodium(I11) hydrido complex seems to be followed by reductive elimination of HCl resulting Rh(CO)(PPha)(SPPlQ.
