Ph3PCMe2CS2−, which reacts to bis(isopropylidene)-1,2,4-trithiolane by thermal or, coordinated to transition metals, photochemical activation according to a cycloaddition mechanism. By reaction of the betaine with manganese and rhenium carbonyl halides under exclusion of light, stable monomeric and dimeric fac-tricarbonyl complexes with the composition (CO)3M̄(X)S2CCMe2PPh3 (M = Mn, Re; X = Cl, Br) are obtained
作为强亲核试剂,磷基很容易攻击杂丙二烯。在加入异亚丙基三苯基正膦的二硫化碳得到的两性离子加合物博士3 PCME 2 CS 2 - ,其中起反应对双(异亚丙基)-1,2,4- trithiolane通过热或,配位到过渡金属,光化学活化根据环加成机制。通过下的光的,稳定的单体和二聚体排斥与锰和铼羰基卤化物甜菜碱反应FAC与组合物(CO)三羰络合物3 M(X)s 2 CCME 2 PPH 3得到(M = Mn,Re; X = Cl,Br),其通过其光谱(IR,NMR,UV)区分。单体溴锰和-配合物是同构的,并且在空间群P2 frcase1 / c(单斜晶系,Z = 4)中结晶。
