A range of new π-conjugated ethynyl- and diethynyl-benzene ligands has been synthesised and their spectroscopic characterisation carried out, most notably via IR and 1H NMR. X-ray crystal structures were obtained for three of these ligands and
A Stereoselective Synthesis of Olefins by a New Semi-stabilized Phosphonium Ylide

A new semi-stabilized phosphonium ylide, viz. (9-anthrylmethylene)triphenylphosphorane (2) generated by the action of sodium hydride or sodamide in benzene or sodium methoxide in methanol on (9-anthrylmethyl)triphenylphosphonium bromide (1), has been reacted with substituted aromatic aldehydes (3) to give exclusively the trans-1-(9-anthryl)-2-substituted-arylethylenes (4).The variation of solvents and bases has no effect on the stereoselectivity of the reaction.The trans-geometry of 4 has been established by IR and PMR spectral data.
