Abstract
The aminium salts-induced dimerization of alfa-methylstyrene lb gives rise, depending on the solvent employed, to high yields of 1,3,3-trimethyl-1-phenylindane 2b, or 2,4-diphenyl-4-methyl-l-pentene 6b. Several 1-aryl-l-phenylethylenes la,c-e afford, instead, cyclodimers 2a,c-e, or 2,5-diaryl-2,5-diphenyltetrahydrofuran derivatives 3a,c-e.File in questo prodotto:
