solvated rhodium (I) complex [Rh(cod)Sx]BF4 to afford the cationic complex [Rh(cod)η2-S,P-Ph2P(S)N(CHMePh)PPh2}]BF4 (3). However, when the above reaction was carried out with 2, cleavage of the CN bond of the ligand occurred, to yield the complex [Rh(cod)(η2-S,S-Ph2P(S)}2NH)]BF4 (4). Reactions of 1 with the fragments of Rh (III) and Ir (III) [Cp*MClSx]BF4 lead to cleavage of the CN bond of the ligand
S-(Ph 2 P)2 N(CHMePh)与硫(摩尔比为1:1)在乙醚溶液中的反应生成S-Ph 2 P(S)N(CHMePh)PPh 2(1)。当反应在四氢呋喃中以过量硫(摩尔比为1:5)进行时,获得二硫化物S- Ph 2 P(S)} 2 N(CHMePh)(2)。1种发生反应与溶剂化铑(I)配合物的[Rh(COD)s X ] BF 4,得到阳离子络合物的[Rh(COD)η 2 -S,PPH 2 P(S)N(CHMePh)PPH 2 }] BF 4(3)。然而,当在上述反应用下进行2,发生配位体的CN键的裂解,以产生复杂的[Rh(COD)(η 2 -S,S- 博士2 P(S)} 2 NH)] BF 4(4)。的反应1与铑(III)和Ir(III)的片段的[Cp * MCLS X ] BF 4导致配体的CN键的裂解,得到阳离子络合物,[(CP *)的MC1 η 2 - P,S-PH
