摘要：

We synthesized and characterized two ligands, 2-(quinolin-8-yl)thiophene (1a) and 3-(quinolin-8-yl)thiophene (1b). The selective C-H activation of the thiophene moieties was achieved by reacting 1a or, 1b and [Pt(CH3)(2)(SMe2)](2). We observed eta(2)-thiophene intermediates during the course of the reactions. The selective C-S bond activation of the thiophene moieties was observed after reacting 1a or 1b and [Pt(dippe)H](2). DFT calculations were performed to elucidate the regioselectivity of C-S activations.
