Zirconocene-Catalyzed Alkylation of Aryl Alkenes with Alkyl Tosylates, Sulfates, and Bromides. -Primary and secondary alkyl groups can be introduced regioselectively at the benzylic position of styrenes by alkylation in the presence of catalytic amounts of zirconocene catalysts.

The electron impact (EI) mass spectra of allyl aryl selenides showed abundant molecular ions and many fragment ions containing the selenium atom. a-Cleavage is the dominant process in the fragmentation of selenides, and cleavage product ions are characteristic of the substituents. In the case of 3-m
Fragmentation pathways of the title compounds under electron impact were compared to those of their (1aryl)substituted analogs reported earlier. The main fragmentation route of the M ร ions is the sulphamide N-S bond cleavage leading to [M ร ArSO 2 ] ions. No loss of the alkyl substituents from the
