As strong nucleophiles, phosphorus ylids easily attack heteroallenes.The addition of isopropylidene triphenylphosphorane to carbon disulfide yields the zwitterionic adduct Ph3CMe2CS2-, 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)3(X)S2CCMe2Ph3 (M=Mn, Re; X=Cl, Br) are obtained which are distinguished by their spectra (IR, NMR, UV).The monomeric bromomanganese and -rhenium complexes are isomorphous and crystallize in the space group P21/c (monoclinic, Z=4).
