Abstract
A series of tin(II) complexes 2–5 bearing 1,3,5-triazapentadienyl ligands are reported: Sn[N(Ph)C(R′)NC(R′)N(SiMe3)]2 [R′ = 1-piperidino, 2; NMe2, 3], [N(Ph)C(NMe2)NC(NMe2)N(H)]SnCl (4) and [{N(SiMe3)C(R′)NC(R′)N}2Sn2]2 (R′ = 1-piperidino) (5). Their single-crystal X-ray diffraction studies are presented. Compounds 3 and 4 are efficient catalysts for the catalytic addition of phenylamine to N,N'-diisopropylcarbodiimide giving guanidine.
