the alkylating esterification of the corresponding 1-hydroxy derivatives under phase transfer catalytic, microwave, and solventless conditions using alkyl halides as the reactants and potassium carbonate as the base. In the case of alkylating agents of increased reactivity, there was no need for the use of phase transfer catalyst. Regarding the phosphinic acids, the 3-methyl-3-phospholene oxides were
以卤代烷为反应物,碳酸钾为碱,在相转移催化、微波和无溶剂条件下,通过相应的 1-羟基衍生物的烷基化酯化反应合成了 1-烷氧基-3-磷烯 1-氧化物。在反应性增加的烷基化剂的情况下,不需要使用相转移催化剂。关于次膦酸,3-甲基-3-磷烯氧化物比3,4-二甲基衍生物更具反应性。应用碳酸铯,3-磷烯氧化物异构化为2-磷烯也发生了。© 2010 Wiley Periodicals, Inc. 杂原子化学 21:211–214, 2010; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20596
