A process for the preparation of 6-fluoro-2-methyl-l-indanone which relates to a process of preferential cyclization of (3-fluorophenyl)-isopropenyl-ketone to obtain 6-fluoro-2-methyl 1-indanone regioisomer with respect to 4-fluoro-2-methyl-l-indanone regioisomer, is described.
homologation of unstrained aryl ketones through a formal 1,1-insertion process of olefins, enabled by temporary directing group (TDG)-aided C–C activation. The reaction provides a distinct approach to access various substituted 1-indanones. Computational mechanistic studies reveal that the formal 1,1-insertion is realized by a selective C(sp2)–C(sp3) activation and turnover limiting 2,1-insertion into
