Substituted vinylphosphonates also behave as Nhchael acceptors. Thus, phenyl-. 2-thienyl-. 2-pyridyl, and 1-naphthylacetonitriles add to tetraethyl ethenylidenediphosphonate under DBU conditions in THF,- and ethyl cyanoacetate adds to dietliyl 2-(ethoxycarbonyl)vinylphosphonate under basic condi tions. In both cases, the corresponding addition products are isolated in low to moderate yields. [Pg.278]

Scheme 8.12 shows a simple, efficient, and enviTomnentlly eco-friendly route for the synthesis of yUdenenitriles of 4-oxo-(4//)-l-benzopyian-3-caibaldehyde by the condensation of 4-oxo-(4//)-l-benzopyran-3-caibaldehyde with active methylene compounds viz. malononitrile, cyanoacetic add, and cyanoacetamide in distilled... [Pg.239]

In the presence of tributylphosphine, copper(i) cyanoacetate adds carbon dioxide reversibly to form [Cu(OCOCH2CN)PBu3] which reacts with cyclohexanone and allyl bromide to give allyl l-allylcyclohexa-2-one. A Cu promoted conversion of carbon dioxide into urethanes has been developed (Scheme 7). ... [Pg.430]
