Light-induced stereospecific intramolecular [2+2]-cycloaddition of atropisomeric 3,4-dihydro-2-pyridones
Atropisomeric 3,4-dihydro-2-pyridones undergo stereospecific [2+2]-photocycloaddition in solution with high stereoselectivity (ee > 98% and de > 96%) in the product. The chiral transfer during phototransformation was rationalized based on the stability/reactivity of the biradical.

Dihaloiodates(I): Synthesis with hydrogen peroxide and their halogenating activity
Tetraalkylammonium and pyridinium dichloro- and dibromoiodates(I) were efficiently prepared from iodine and tetralkylammonium chloride or pyridine by oxidation with hydrogen peroxide in the presence of an equimolar amount of a hydrogen halide. Their halogenating activity was tested on 1,3-dimethoxybenzene and styrene as model substrates. The results show that ICl2 - salts acted as iodinating reagents, while IBr2 - salts brominated both substrates. 2012 Elsevier Ltd. All rights reserved.
