Highly active g-C3N4 as a solid base catalyst for knoevenagel condensation reaction under phase transfer conditions
In a promising approach, heterogeneous g-C3N4 as a solid base catalyst exhibits appreciable activity in Knoevenagel condensations at room temperature for the synthesis of substituted stilbene in presence of a crown-ether phase transfer catalyst. High yield of the product substituted stilbene were isolated in a very short reaction time period (~30 min). The solid base g-C3N4 catalyst was proven to be recyclable for several runs. Various aromatic substrates were screened using heterogeneous base g-C3N4 catalyst, exhibiting appreciable corresponding product yield (~99%) at room temperature.

Nucleophilicities of the anions of arylacetonitriles and arylpropionitriles in dimethyl sulfoxide
(Chemical Equation Presented) The rates of the reactions of the colored para-substituted phenylacetonitrile anions 1a-c and the pfienylpropionitrile anions 2a-c with Michael acceptors (3a-u) were determined by UV-vis spectroscopy in DMSO at 20°C. The reac
