Hydrotris-(methimazolyl)borato alkylidyne complexes of tungsten

Abstract

The syntheses of the alkylidyne complexes [W(≡CR)(CO)2{HB(mt)3}] (R = NiPr2 1a, C4H3S-2 1b, C≡CCMe3 1c, C6H4Me-4 1d, C6H3Me2-2,6 1e, C5H4Mn(CO)3 1f; mt = 2-mercapto-3-methylimidazolyl) are reported. The crystal structures of three examples (1a, 1b, an Show more
