Synthesis and reactivity of selenium functionalised allylidynes and propargylidynes

Hill, Anthony; Manzano, Richard; Ward, Jas


The reactions of the trimethylsilylpropargylidyne [W(=CC=CSiMe3)(CO)(2)(Tp*)] (1: Tp* = hydrotris(dimethylpyrazolyl) borate) towards selenium centred reagents when treated with tetrabutylammonium fluoride (TBAF) were explored in order to prepare alkynylselenolato propargylidynes, e.g., [W(=CC=CSePh)(CO)(2)(Tp*)]. Treating 1 with TBAF and PhSeSePh resulted in E and Z isomers of the vinyl-carbyne (allylidyne) complex [W{=CC(SePh)=CHSePh}(CO)(2)(Tp*)] in addition to traces of the trisubstituted...[Show more]
