The synthesis of 5-alkyl-5H-dibenzophosphole 5-oxides has been re-studied. Ethyl-, dodecenyl- and heptadecyldibenzophosphole oxides have been synthesised by the alkylation of the P-methylide generated by lithiation of 5-methyl-5H-dibenzophosphole 5-oxide. An improved method for the synthesis of the latter oxide is also described.
对5-烷基-5H-二苯并呋喃5-氧化物进行了重新研究。通过5-甲基-5H-二苯并呋喃5-氧化物锂化产生的P-亚甲基的烷基化,合成了乙基、十二烷基和十七烷基二苯并呋喃氧化物。还描述了合成后一种氧化物的改进方法。
