nitrilimines to indanone-enamines has been established. The pseudoazulenes are protonated on the five-membered carbon ring. Azo-coupling, tropylation, formylation, and condensation with p-dimethylaminobenzaldehyde has been carried out on the diphenyl-compound; the structures of the products and of their conjugate acids are discussed. Attempts to synthesise the ortho-quinonoid 2-methyl-1,3-diphenylindeno[1
已经制备了2-甲基-1,3-二苯基茚并[2,1- c ]吡唑及其3-乙氧基羰基类似物,其为含有两个稠合的五元环的新型假氮杂腈系统的衍生物。已经确定了将亚硝胺添加到茚满酮-烯胺中的方向。在五元碳环上将假azulenes质子化。已在二苯基化合物上进行了偶氮偶联,对乙酰化,甲酰化和与对二甲基氨基苯甲醛的缩合反应。讨论了产物及其共轭酸的结构。描述了尝试合成邻-醌型2-甲基-1,3-二苯基茚并[1,2- c ]吡唑和苯型2-乙基-3-苯基茚并[1,2- d ]异恶唑的尝试。
Probing the Dynamic Features of Bis(aminocyclopentadienyl) and Bis(aminoindenyl) Zirconium Complexes
cyclopentadienamines 2a and 2b. Subsequent deprotonation with n-butyllithium followed by the reaction with zirconiumtetrachloride led to the formation of the amino-substituted bent metallocenes 4a and 4b. Crystallization furnished the isomerically pure complex meso-bis(phenyl-3-pyrrolidinylcyclopentadienyl)zirconium dichloride (meso-4b), which was characterized by X-ray diffraction. Complex meso-4b exhibits a
