The reactions of an unsubstituted vinamidinium salt with organometallic reagents, borane, and DIBAL-H are described. The products of these reactions were unsaturated aldehydes, and allylic amines. The reaction conditions and possible mechanistic implications are also discussed.

A series of o-phenylenediamines and o-aminophenols have been reacted with Gold's reagent to yield benzimidazoles and benzoxazoles, respectively. Additionally, o-hydroxyacetophenone and anthranilamide, when reacted with Gold's reagent, were found to produce chromone and 3H-quinazoline-4-one, respectively. These transformations represent the use of Gold's reagent as a one atom lynch pin.

Substitution par reaction de nitro- et fluoro-, benzonitrile, -diphenylsulfone, -benzophenone, benzaldehyde, -acetophenone, -benzamide, -benzene-sulfonamide avec des polyfluoroalcanolate de sodium

Irradiation of the ring A unsubstituted 6/5-fused cross-conjugated cyclohexadienone (1a) and its 2-methyl derivative (1b) in methanolic acetic acid yields, in addition to other products, novel tricyclononane derivatives which have been assigned the structures (3a) and (3b).
