Condensation of lactam acetals 2a,b with isocyanacetic esters give 3a,b.The Z-configuration of 3a (R1=CH3, R2=C2H5) was determined by X-ray diffraction.Reaction with ethyl N-(ethoxycarbonyl)glycinate gives the protected α,β-dehydroam

Isocyanide platinum(II) complexes trans-+Cl- (2) (L = vinylogous aminoisonitrile are formed from cis-(Ph3P)2PtCl2 and L; the cations of 2 have been isolated as PF6- salts (3).At higher temperatures the salts 2 give the neutral complexes cis-(Ph3P)LPtCl2 (4) and PPh3.Treatment of 4 with amines HNR2R3 affords the diaminocarbene complexes cis-1HN)(R2R3N)C>PtCl(amine)>+Cl- (isolated as PF6- salts 5) which on heating give the compounds cis-(Ph3P)1HN)(R2R3N)C>PtCL2 (7).
