Abstract

A new series of bis (acetylide) organic ligands having fluorene or fluorenone moieties in the backbone, 2, 7-di (trimethylsilylethynyl) fluorene (1a), 2, 7-di (ethynyl) fluorene (1b), 2, 7-di (trimethylsilylethynyl) fluoren-9-one (2a) and 2, 7-di (ethynyl) fluoren-9-one (2b), has been prepared. Reaction of the diterminal alkynyl fluorene derivatives 1b and 2b with two equivalents of the complex trans-[(Ph)(PEt3) 2Pt (Cl)] in CH2Cl2/iPr2NH with catalyic CuI ...
