The amide base generatedin situfrom tetramethylammonium fluoride and N(TMS)3catalyzes the synthesis of 1,3-diene from an allylbenzene and carbonyl compound. The system is applicable to the transformations of a variety of allylbenzenes with functional groups (halogen, methyl, phenyl, methoxy, dimethylamino, ester, and amide moieties). Acyclic and cyclic diaryl ketones, pivalophenone, pivalaldehyde, and isobutyrophenone are used as coupling partners. The role oftransβ-methyl stilbenes in product formation is also elucidated.

Two new xanthenyl ylids, viz. triphenylphosphoniumxanthen-9-ylid and triphenylphosphoniumthioxanthen-9-ylid have been prepared.The former undergoes normal Wittig reaction with a number of carbonyl compounds yielding olefins.
