Combined use of elevated pressure in the liquid phase (15kbar), a metal template and the sulfur nucleophilicity of [Pt2 (μ-S) 2 (P–P) 2](P–P= diphosphine or 2· monophosphine) facilitates the one-pot synthesis of 3, 8-dibenzo-1, 6-dithiacyclodecane. Under rtp, nucleophilic addition of [Pt2 (μ-S) 2 (P–P) 2][P–P= 2· PPh3; Ph2P (CH2) nPPh2, n= 2, 1, 2- bis (diphenylphosphino) ethane (dppe), 3, 1, 3-bis (diphenylphosphino) propane (dppp)] ...
