Transformation of manganese acyls (CO){sub 5}MnC(O)CH{sub 2}R (R = H, CH{sub 3}, OCH{sub 3}) into their siloxyvinyl derivatives (CO){sub 5}MnC(OSiEt{sub 3}){double_bond}CHR with triethylsilane. An approach to double carbonylation of manganese alkyl complexes (CO){sub 5}MnCH{sub 2}R
- Rensselaer Polytechnic Inst., Troy, NY (United States). Dept. of Chemistry
Treatment of the manganese acyl complexes (CO){sub 5}MnC(O)CH{sub 2}R [R = H (1a), CH{sub 3} (1b), OCH{sub 3} (1c)] with triethylsilane gave stable {alpha}-triethylsiloxyvinyl compounds (Z)-(CO){sub 5}MnC(OSiEt{sub 3}){double_bond}CHR (3a-c). Carbonylation of 3a and 3b, followed by protonolysis of the resulting (CO){sub 5}MnC(O)C(OSiEt{sub 3}){double_bond}CHR [R = H (5a), CH{sub 3} (5b)] provided their {alpha}-ketoacyl derivatives (CO){sub 5}MnC(O)C(O)CH{sub 2}R (6a and 6b), which represents a net double carbonylation of their alkyl precursors (CO){sub 5}MnCH{sub 2}R.
