✦ Synopsis

Recognition of the role of x-complexed olefins end other metal organic intermediates in catalytic hydrogenation (1) led us to consider the case of cyclopropanee for which x-bonded intermediates have been recognised in chemical reactions (2) and inferred in catalytic hydrogenation (3). By means of the displacement reaction: (i) (C2Hq PtC12j2 + cyclopropane * C2H4 + (cyclopropane PtC12)n we were abletoprepare PtC12 complexes of the substituted cyclopropanes [21 -C61. These derivatives formed pale yellow to white,rather insoluble,solids which are clearly chlorine bridged polymers. The derived Ccyclopropanel PtC12(C5H5N)2 complexes, however, could be crystallised, and by T.L.C. on silica behaved as single substances. l,l-Diphenylcyclopropane [71 gave a more soluble product Ph2C3$PtClr i.e. the r-ally1 derivative C81. All the complexes on analysis gave C,H,Cl and Pt percentages in very good agreement with the required
