Abstract

3, 4-Dichalcogenopenta-2, 4-dienylation of aldehydes proceeded in good to high yields using 4-ethoxy-1-(benzenesulfenyl)-2-(methanesulfenyl)-(5), 4-ethoxy-1, 2-bis (benzenesulfenyl) but-1, 3-diene (6), and 1-selenenyl derivatives 7 and 8. This novel four- carbon homologation could be applied to a synthesis of 3, 4, 7, 8-tetrakis (benzenesulfenyl)- 10, 10-dimethylundeca-2, 4, 6, 8-tetraenal (20).
