phosphaalkenes (1 and 2) with 1,3 dienes such as methyl sorbate and 1-methoxy 3-trimethylsilyloxy-1,3 butadiene leads to functionalized λ3 phosphabenzenes 6, 9, 12, 13 and 16 after aromatization of the primary adducts. The aromatization may occur either spontaneously or after chemical transformations. The reversible cycloaddition has allowed the synthesis of isomeric phosphabenzenes 6 and 9. Diels-Alder
所述phosphaalkenes的(反应1和2)与1,3-二烯类,如甲基山梨酸和1-甲氧基-3-三甲基甲硅烷基-1,3-丁二烯导致官能λ 3个phosphabenzenes 6,9,12,13和16的主要的芳构化后加合物。芳香化可以自发发生,也可以在化学转化后发生。可逆的环加成反应允许合成异构的磷苯6和9。与phosphaalkenes Diels-Alder反应似乎是官能化的λ获得方法的一般方法3个phosphabenzenes。
