ABSTRACT
Some a-benzylidene-g-arylDb,g,butenolides (I) were synthesised and their reactions with different nucleophiles were investigated. The attempt to prepare the corresponding acyl azides (V) from the starting butenolides, via the acid hydrazides (11), failed. This led to an alternative route where the azides (V) were prepared from the corresponding acid chlorides. The behaviour of these azides under different experimental conditions was also investigated.
