Deprotonation of rhenium terminal acetylide complexes of the formula ({eta}{sup 5}-C{sub 5}R{sub 5})Re(NO)(PPh{sub 3})(C{triple_bond}CH): Generation and reactivity of rhenium/lithium C{sub 2} complexes
- Univ. of Utah, Salt Lake City, UT (United States)
Reactions of methyl complexes ({eta}{sup 5}-C{sub 5}R{sub 4}R`)Re(NO)(PPh{sub 3})(CH{sub 3})(R/R` = H/H,H/CH{sub 3}, CH{sub 3}/CH{sub 3}) with HBF{sub 4}{lg_bullet}OEt{sub 2}, chlorobenzene, and R{double_prime}C{triple_bond}CH (R{double_prime} = H, CH{sub 3}) give terminal alkyne complexes [({eta}{sup 5}-C{sup 5}R{sub 4}R`)-Re(NO)(PPh{sub 3})(R`C{triple_bond}CH)]{sup +}BF{sub 4}{sup -}{sub 4} can be effected at 90-65{degrees}C (75-99% conversion). Treatment of the alkyne or vinylidene complexes with T-BuO{sup -}K{sup +} gives acetylide compleses. 34 refs., 1 tab.
