REGIOSELECTIVITY OF REDUCTION OF 2-tert-BUTYL-1-BENZOPYRILIUM PERCHLORATE
Suzdalev, K.F.,Koblik, A.V.
, p. 258 - 260 (1989)
The reaction of 2-tert-butyl-1-benzopyrilium perchlorate with various reducing agents leads to a mixture of 2H- and 4H-chromenes.The greatest selectivity (90percent 2-tert-butyl-4H-chromene and 10percent 2H-isomer) was achieved using 1,3-dimethylbenzimida
