The phenyl-platinum(II) organocyanamide trans-[Pt(Ph)(NCNR 2)(PPh3)2][BPh4] (R=Me 1a, Et 1b) or cyanoguanidine cis-[Pt(Ph){NCNC(NH2)2}(PPh 3)2][BPh4] (2) complexes have been prepared by treatment of cis-[PtCl2(PPh3)2] in THF with NCNR2 or NCNC(NH2)2, respectively, in the presence of Na[BPh4], whereas the cyanoguanidine chloro-complex cis-[PtCl{NCNC(NH2)2}(PPh3)2] [BF4] (3) has been obtained by using Tl[BF4] instead of Na[BPh4]. Complex 3 reacts further with cyanoguanidine, in the presence of Na[BPh4], to produce the di(cyanoguanidine) cis-[Pt{NCNC(NH2)2nf>)2][BPh 4]2 complex 5, whereas the amine complex cis-[PtCl(NH 2R′)(PPh3)2][BF4] (R′=CH2C6H4Me-4, 4) is formed on reaction of the former with NH2R′ in CH2Cl 2. The X-ray structure of 1a is also reported.

trans-Diarylbis(triphenylphosphane)platinum(II) (aryl = C6H5, 3-CH3C6H4, 4-CH3C6H4, 3-CH3OC6H4, 4-CH3OC6H4, 3-(H3C)2NC6H4) (trans-1a - f) have been synthesized.The trans-configuration in this type of compounds is demonstrated by an X-ray analysis of the parent compound trans-.The thermolysis of trans-1a - f yields - despite the trans-position of the phenyl rings - stereospecific reductive elimination of the biphenyl system in a concerted reaction.
