compounds is described. The latter are converted by various routes into either [(allyl)Fe(CO)4]+ - or [(dienyl)Fe(CO)3]+ - derivatives. The allylic cations, when reacted with P (C6H5)3, yield uncomplexed (2-en-l-yl)triphenylphosphonium salts in good yields, while treatment of the dienyl cations with P(C6H5)3 leads to the quantitative formation of (2,4-diene-l-yl)triphenylphosphonium ions still coordinated
描述了从(二烯烃)三羰基铁化合物开始的β-烯烃三苯基phosph盐的区域和立体定向制备。后者通过各种途径被转化为[(烯丙基)Fe(CO)4 ] + -或[(二烯基)Fe(CO)3 ] + -衍生物。当与P(C 6 H 5)3反应时,烯丙基阳离子以高收率产生未络合的(2-en-1-基)三苯基phosph盐,而用P(C 6 H 5)3处理二烯基阳离子则导致仍与Fe(CO)3配位的(2,4-二烯-1-基)三苯基phosph离子的定量形成-部分。描述了一种氧化分解的方法,通过该方法可以得到游离的salts盐。
