(Chemical Equation Presented) Dimethyl sulfoxide (DMSO) efficiently causes the reductive elimination of 3-aryl 2,3-dibromopropanoates to cinnamates with good yield. With 3-phenyl 2,3-dihalopropanoates, debromination is the major pathway providing 3-phenylacrylate derivatives in high yields, whereas dehydrobromination is a competing pathway with thiophene derivatives. 1H NMR, 81Br NMR, and MS techniques indicated the formation of brominated-DMSO, MeBr, and HBr as byproducts in this transformation with no evidence for the formation of Br2. The dual role of DMSO as a nucleophile and bromine scavenger accounts for the products formed in this reaction.

The excited-state reaction of push-pull styryl system was studied in this work. In the excited state, compounds of 2-StP-NMe2, 2-StQ-NMe 2, 4-StQ-NMe2 and 4-StP-NMe2 possess a sufficiently large acidity change f
