1H-Cyclopropa[b]naphthalene 7 is converted into a range of 6π 5-atom-substituted methylidene derivatives 12e–j, the pyridyl analogues 12k and 1, and the phenylsulfanyl analogue 12m by way of the 1,1-disiIyl compound 9 and Peterson olefination in improved procedure. The spectroscopic properties of the compounds are reported and their behaviour as possible lumophores assessed. Crystal structures of the
1 H-环丙烷[ b ]萘7通过1,1-二甲苯基化合物9转化为一系列6π5原子取代的亚甲基衍生物12e – j,吡啶基类似物12k和1和苯硫基类似物12m。Peterson烯烃的改进工艺。报告了化合物的光谱性质,并评估了它们作为可能的荧光团的行为。呈现了二甲基氨基苯基12c,d和噻吩基12e衍生物的晶体结构。单取代12e的永久偶极矩和k分别测得为2.76和3.37 D,二噻吩基12f的测得为9.06 D.
