the ligands L1 (= MeP(SMe)2) and L2 (= CF3P(SMe)2) have been studied by synthesis and spectroscopic investigations (IR, NMR, MS) of their chromium, molybednum and tungsten complexes M(CO)5L (M = Cr, Mo, W, L1: 1–3; L2: 4–6 and M(CO)4L2 (L1: 7–9; L2: 10–12. Complexes 1–6 are obtained by indirect photochemical substitution via M(CO)5THF, compounds 7–12 by replacement of norbornadiene (NBD) in M(CO)4NBD
配位体L 1(= MeP(SMe)2)和L 2(= CF 3 P(SMe)2)的配位性质已通过其铬,钼和四价铬的合成和光谱研究(IR,NMR,MS)进行了研究。钨络合物M(CO)5 L(M =铬,钼,W,L 1:1 - 3,L 2:4 - 6和M(CO)4大号2(L 1:7 - 9,L 2:10 – 12。配合物1 –6是通过间接光化学取代通过M(CO)得到的5 THF,化合物7 - 12在M(CO)替换降冰片二烯(NBD)的4 NBD。光谱数据[η(CO),Δδ]支持MP键的σ-供体/π-受体模型以及除诱导和空间效应外的介晶的影响。
