Intra- and inter-molecular phosphoryl migration in phosphinothiazolines; precursors to polynuclear complexes and bimetallic coordination polymers

Two tautomers of the new phosphinoaminothiazoline Ph2PNHC=NCH2CH2S, obtained from the reaction of 2-amino-2-thiazoline (ATHZ) with Ph(2)PCl, have been structurally characterized and the intermediate formation of the diphosphine Ph2PN=CN(PPh2)CH2CH2S has been demonstrated experimentally and by DFT calculations; reacts with AuCl(THT)] to give (AuCl)2] whereas the bidentate metalloligand cis-Pt(1(-H))2] reacts with AgOTf to form the Ag-Pt coordination polymer Ag(infinity)Pt(1(-H))2](infinity)](OTf)(infinity).
