Usage: |

Keyword: |
GAMMA-ADDITION REACTION; BAYLIS-HILLMAN REACTION; DIMETHYL ACETYLENEDICARBOXYLATE; WITHDRAWING GROUP |
Remarks: |
The development of some new synthetic reactions derived from nucleophilic addition of phosphines to electron-deficient carbon-carbon triple bonds is described. These reactions show that the phosphine plays the role of a nucleophile as well as an excellent leaving group. The central problem is to generate a 1,3-dipole from atkynoates or allenoates; (2,3-butadienoates) by interaction with various phosphines. This study illuminates the unusual phenomena and shows how this understanding allows control of the reaction.
