Reactions of the bis-carbenium ion 2,2′-bis[bis(p-methoxyphenyl)methyl]biphenyl ditetrafluoroborate with ammonia, n-propylamine and benzylamine have been studied with the aim of developing an acid-labile protecting group for primary amines that masks both
Acid-catalyzed cyclization reactions of 2,2′ -bis(diarylhydroxymethyl)biphenyls to 5,5,7,7-tetraaryl-5,7-dihydrodibenzo[c,e]oxepins in the solid state
