Abstract
Fluoro-, chloro- and bromostannylphosphines (8-10) complexed on phosph orus by tungsten pentacarbonyl have been synthesized by reaction betwe en lithium mesityl(tungsten pentacarbonyl)phosphide 4 and the correspo nding dihalo(diisityl)tin (isityl: 2,4,6-triisopropylphenyl). Reaction of 8 with tert-butyllithium afforded the stable lithium fluorostannyl phosphide 11. Addition of Me3SiCl or MgBr2 to 11 gave the correspondin g chloro- and bromoderivatives 14 and 15. Similar compounds 16 and 17 were obtained from 9 and 10 and DBU. 11, 14, 15, 16 and 17 present a l arge (1)J(SnP) coupling constant (2099.0 to 2151.4 Hz) indicating a pa rtial Sn-P double bond.
