Symmetrical and Asymmetrical Cyclopropenones: Synthesis and Study of Their Chemical Reactivity
نویسنده
چکیده
Symmetrical and asymmetrical cyclopropenones with diferrocenyl, diaryl and aryl-ferrocenyl substituents were obtained and their chemical behavior was studied. 1-Ethoxy-2,3-diarylcyclopropenylium terafluoroborate selectively reacts with MeLi, n-BuLi with formation of the 3,3-dialkyl-1,2-diarylcyclopropenes. The structures of 2,3-bis(4methoxyphenyl) cyclopropenone (10), 2-ferrocenyl-3-(4-methoxyphenyl) cyclopropenone (11), 2-ferrocenyl-3(naphthalen-1-yl) cyclopropenone (14) and 3,3-dimethyl-1,2-dianysol cyclopropene 19a were confirmed by X-ray crystallographic analysis.
