Abstract
The phenyl-platinum(II) organocyanamide trans-[Pt(Ph)(NCNR2)(PPh3)2][BPh4] (R=Me 1a, Et 1b) or cyanoguanidine cis-[Pt(Ph){NCNC(NH2)2}(PPh3)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)2}2(PPh3)2][BPh4]2 complex 5, whereas the amine complex cis-[PtCl(NH2R′)(PPh3)2][BF4] (R′=CH2C6H4Me-4, 4) is formed on reaction of the former with NH2R′ in CH2Cl2. The X-ray structure of 1a is also reported.
