New ferrocene and cobaltocenium acetal and aldehyde containing compounds have been prepared. The acid catalysed condensations of both metallocene bis(aldehydes) (5, 6) with 1,3-dihydroxybenzene yielded complex products. The new metallocene cyclic monoaldehydes (7, 8), differed markedly in their reactions with 1,3-dihydroxybenzene with the ferrocene derivative 8 producing [1+1] and [1+2] bisphenol:
已经制备了新的二茂铁和钴ce缩醛和醛的化合物。茂金属双(醛)(5、6)与1,3-二羟基苯的酸催化缩合产生复杂产物。新的茂金属环状单醛(7,8)与1,3-二羟基苯与二茂铁衍生物8产生[1 + 1]和[1 + 2]双酚:醛加成物的反应显着不同,而钴ce类似物给出了环状二烯化合物(16)。还描述了16的单晶X射线结构,并报道了一些新的茂金属衍生物的电化学性质。
