have been observed to have often low reactivity towards neutral transition metal organometallic systems. When reactions do occur they usually involve salt eliminations and formation of complex mixtures containing inter alia organic sulfides, disulfides, freed ligands or their oxides and reduced forms of the organometallic reactants. From the sulfinyl ylide [PhS(O)CH2]Li, exo-[η5-C6H6CH2S(O)Ph]Mn(CO)3
已观察到亚磺酰基碳负离子[RS(O)CHR'] - Li +(R = Ph,Me; R'= H,Ph)对中性过渡金属有机金属体系的反应活性通常较低。当确实发生反应时,它们通常涉及除盐和形成复杂混合物,所述混合物尤其包含有机硫化物,二硫化物,游离的配体或其氧化物以及还原形式的有机金属反应物。从亚磺酰基叶立德[PHS(O)CH 2 ]栗,外切- [η 5 -C 6 ħ 6 CH 2 S(O)PH]的Mn(CO)3和新metallocyclic化合物(η 5 -C 5 H ^ 5)2TICH 2 SC 6 H ^ 4已经制备,检查后者的一些性质和它的锍衍生物[(η 5 -C 5 H ^ 5)2 TiCH2S(ME)C6H 4 ] BF 4隔离。
