Abstract

Reagents for one-step construction of conjugated bromodienes from aldehydes are described. Various 1-alkyl- and 1-aryl-tetrazoyl bromoallylic sulfones were synthesized and evaluated in bromodiene synthesis. 1-Alkyl-tetrazoyl sulfones selectively afforded (1E,3Z)-bromodienes, while 1-aryl-tetrazoyl sulfones resulted in low selectivity.
