Transition metal enolate chemistry. Formation of a palladium alkyl complex from a highly reactive enolato palladium complex
Abstract
The ester-derived palladium enolate [LPd{Ph2PCH![[double bond, length half m-dash]](https://www.rsc.org/images/entities/char_e006.gif) C(O)OEt}]1(L =o-C6H4CH2NMe2) reacts instantly with dimethyl acetylenedicarboxylate and tetracyanoethylene in tetrahydrofuran (THF) to yield respecitively the alkenyl complex [LPd{Ph2PCH[C(O)OEt](MeO2CC
C(O)OEt}]1(L =o-C6H4CH2NMe2) reacts instantly with dimethyl acetylenedicarboxylate and tetracyanoethylene in tetrahydrofuran (THF) to yield respecitively the alkenyl complex [LPd{Ph2PCH[C(O)OEt](MeO2CC![[double bond, length half m-dash]](https://www.rsc.org/images/entities/char_e006.gif) CCO2Me)}]2 and the alkyl complex [LPd{Ph2PCH[C(O)OEt][(NC)2CC(CN2)]}]3.
