Conjugated arylacetylenic ketones and aldehydes, propargyl-type alcohols, and arylacetylenes reacted with arenes in the presence of AlBr3 or AlCl3 as catalyst to give substituted indenes. 3-Arylpropynoic acids under analogous conditions gave rise to 3,3-diarylindan-1-ones, while the corresponding methyl esters were converted into methyl 3,3-diarylprop-2-enoates. The key intermediates in the transformations
在作为催化剂的AlBr 3或AlCl 3的存在下,共轭的芳基炔基酮和醛,炔丙基型醇和芳基乙炔与芳烃反应,得到取代的茚基。在类似条件下,3-芳基丙酸产生3,3-二芳烃基-1-酮,而相应的甲酯被转化为3,3-二芳基丙-2-烯酸甲酯。炔酮和醛以及炔丙基型醇转化为茚衍生物的关键中间体是共振稳定的炔丙基-烯丙基阳离子-C≡CC + ↔-C + = C = C,它与一个共振结构反应生成异构体取决于取代基的性质。
