Synthesis and thermal reaction of hydrido(selenolato) platinum(II) complex having a 9,10,11,12,14,15-hexahydro-9,10[3′,4′]-furanoanthracenyl group

Abstract

The oxidative addition of selenol, HhfSeH ( 2, Hhf = 9,10,11,12,14,15-hexahydro-9,10[3′,4′]-furanoanthracenyl) with [Pt(η 2-nb)(Ph 3P) 2] (nb = norbornene) in toluene afforded the corresponding hydrido(selenolato) Pt(II) complex [ cis-PtH(SeHhf)(Ph 3P) 2] ( 3) as a stable compound. Refluxing a xylene solution of 3 produced two isomers of five-membered selenaplatinacycles 4 in moderate yield as an inseparable mixture. In addition, the molecular structures of HhfSeH 2 and the minor selenaplatinacycle 4a were determined by X-ray crystallography.
