1,2-Alkatrienephosphonates in the Reactions with Sulfenyl- and Selenenylbromides
摘要:
The interaction of 1,2-alkatrienephosphonic dichlorides and dialkyl esters with sulfenyl- and selenenylbromides is investigated and a possible mechanism of the reactions is discussed. The possibility to control the structure of the products by variation of the type of the electrophile and of the substrate is also shown.

The reaction of dialkyl (3-methylpenta-1,2,4-trienyl)phosphonates with dialkyl esters of acetylenedicarboxylicacid proceeds via a novel spontaneous aromatization of the Diels–Alder adducts leading to benzylphosphonic acid derivatives.
