, p. 823 - 828 (1997)
Starting from methylthioimidates 1-8 a series of corresponding tricyclic β-lactams was synthesized via [2+2]cycloaddition with ketenes generated in situ from substituted acetyl chlorides. Dependent on the bicyclic starting material and on the substituent
Process for the ring chlorination of aromatic hydrocarbons

, (2008/06/13)
Aromatic hydrocarbons which are monosubstituted by straight-chain or branched C1 -C12 -alkyl or by C3 -C8 -cycloalkyl can be chlorinated in the presence of Friedel-Crafts Catalysts in liquid phase on the aromatic ring if cyclic benzo-fused imines or benzo[f]-1,4-thiazepines are used as co-catalysts. This makes it possible to obtain a higher proportion of p-isomers.
