General, convenient and simple syntheses of long straight chain alcohols and carboxylic acids were developed utilizing organoborane chemistry. One of the methods entails the thermal isomerization of long-chain alkyldicyclohexylboranes, followed by oxidation. An alternative procedure for the preparation of long-chain alcohols involves the KAPA isomerization of internal alkynes to the terminal derivative
利用有机硼烷化学方法开发了长直链醇和羧酸的一般,方便和简单的合成方法。一种方法需要长链烷基二环己基硼烷的热异构化,然后进行氧化。制备长链醇的另一种方法涉及将内部炔烃进行KAPA异构化为末端衍生物,然后用9-BBN进行二氢硼化和氧化。或者,末端炔可以直接氧化成羧酸。在另一策略中,通过使用硼烷中间体的高压羰基化来制备C 30-醇三tri吨醇。
