Six stabilised phosphoniumylides bearing ortho-benzylaminophenyl and cinnamoyl (or a heterocyclic analogue) groups have been prepared and upon flash vacuum pyrolysis at 800 °C were found to undergo cascade cyclization processes to give mainly 3-styrylquinolines but also in some cases ring-fused carbazoles and other fused-ring heterocyclic products. By starting with an appropriate ring-methylated precursor
Palladium-catalyzed arylations of styrene and acrylic acid are shown to occur in the presence of base (Na2CO3 or K2CO3) in pure water using simple palladium compounds as catalyst precursors.
