Naik, S. N.,Pandey, B.,Ayyangar, N. R.
, p. 625 - 632 (2007/10/02)
Acylation, benzoylation, toluylation and related reactions of active methylenes, e.g. indene, fluorene and diethylmalonic ester is enhanced by the use of solid-liquid phase transfer catalyst.An interesting rearrangement with phthaloyl chloride is reported under identical conditions.

, p. 195 - 196 (2007/10/02)
A novel photochemistry of ??* triplet of enone (5a) has been applied to the synthesis of a model spiro compound (6a, 85percent) related to fredericamycin A (1).Phase-transfer catalyst, e.g. tetra-n-butylammonium bromide has been used for the di
