摘要

Upon reaction with an excess of 2,2-dimethylpropane-1,3-diol (neopentyl glycol, NPG) under acid catalysis, indan- ones and tetralones yield indenes and dihydronaphthalenes, respectively. The reaction can also be carried out with butane-1,3-diol. ... Keywords: indanones, tetralones, indenes, 1,2-dihydronaphthalenes, alkene synthesis ... The protection of the keto function as a cyclic acetal through its reaction with glycerols is widely used.1 ...
