A composition comprising a compound of formula (Va) wherein n is 1 or 2 and wherein m is 1 or 2, with n and m preferably both being 1 or both being 2, more preferably both being 1, and/or, preferably and, a compound of formula, wherein n is 1 or 2 and wherein m is 1 or 2, with n and m preferably both being 1 or both being 2, more preferably both being 1, and wherein at least 90 weight-% of the composition consist of compounds of formula (Va) and formula (Vb).
Ru(ii)-catalyzed [2 + 2 + 2] cycloaddition of 1,2-bis(propiolyl)benzenes with monoalkynes leading to substituted anthraquinonesElectronic supplementary information (ESI) available: experimental procedures and analytical data. See http://www.rsc.org/suppdata/cc/b3/b301762a/
[2 + 2 + 2] cycloadditions of 1,2-bis(propiolyl)benzenes with monoalkynes were effectively catalysed by Cp*RuCl(cod) under mild conditions to give substituted anthraquinones in moderate to high yields.
