A C-amide-substituted O-silylated oxime, (E)-(tert-butyldimethylsiloxyimino)acetic acid N,N-dimethylamide (8b), on treatment with 2.2 equiv of BF3 center dot OEt2, in situ generated boracyclic nitrone-type intermediate BF3 center dot 14, which und...
Anthracene derivatives possessing a carbamate group and an ester group at their 9- and 10-positions, respectively, were prepared to furnish pairwise packing of anthracene fluorophores in their crystal structures. They were nonluminescent in ethano...
