N-Arylidene-p-aminoacetophenone (I) and N-arylidene-4'-aminochalcones (V) have been converted into a series of substituted β-lactams (III) and 4-thiazolidinones (IV), and pyrazolines (VI, VII) respectively. p-Chloroacetamidoacetophenone (II) has also been converted into series of substituted 4'-piperidino/morpholinoacetoamidochalcones (X) which undergo cyclization on treatment with hydrazine, phenylhydrazine or thiourea to pyrazolines (XI, XII) and pyrimidine-2-thiones (XIII) respectively.The antibacterial and antifungal activities of the compounds have been determined.

The rate constants for the photolytic brominolysis of 22 trans-1,2-diarylcyclopropanes in carbon disulfide relative to an internal standard, p-chlorotoluene, have been determined.The products of the brominolysis are 1,3-dibromo-1,3-diarylpropanes.The rate constants range over 5 orders of magnitude, being enhanced by electrondonating substituents on one or both benzene rings.The quantitative size of the substituent effect (ρ) at either involved carbon center is a function of the substituent at the other center.This fact suggests a continuum of transition-state structures with varying degrees of bond breaking and charge separation.
