reacts with phosphonium ylides, Wittig–Horner reagents, trialkyl phosphites, and Lawesson's reagents to give the olefinic and cyclic products, the phosphonate adducts, the dialkyl phosphate products, the phosphinodithioic acid, and 2,4-dithione products, respectively. Furthermore, the reaction of 3-(phenylimino)pentane-2,4-dione with Wittig, Wittig–Horner reagents and trialkyl phosphite resulted in the formation
摘要 3-(Hydroxyimino)pentane-2,4-dione 与鏻叶立德、Wittig-Horner 试剂、亚磷酸三烷基酯和 Lawesson 试剂反应得到烯烃和环状产物、膦酸酯加合物、磷酸二烷基酯产物、二硫代膦酸、和 2,4-二硫酮产物。此外,3-(苯基亚氨基)戊烷-2,4-二酮与Wittig、Wittig-Horner试剂和亚磷酸三烷基酯的反应导致形成2,5-二烯二酸、二乙氧基磷酸己酸和磷酸盐产物。考虑了可能的反应机制,结构分配基于分析和光谱结果。还报道了一些新化合物的抗菌和抗真菌活性。图形概要
