Herein, a new protocol dealing with the preparation of 1,2-allenyl ketones has been successfully developedviathe reactions of enynes with radicals enabled by dual photoredox/copper catalysis. Based on the results of a deuteration experiment and the competition reaction between cyclopropanation and allenation, the mechanism based on a photoredox-neutral-catalysed radical-polar crossover process has been proposed. Synthetic applications of allenes have also been demonstrated.
GAS-SOLID REACTIONS : PART VI. INTERACTION OF SOLID CHALCONES WITH BROMINE AND IODINE VAPOURS

Solid chalcones (azylidene acetophenones) give, on exposure to bromine vapour at room temperature, the "trans-adduct" in quantitative or near-quantitative yield.Polymorphic forms of several compounds do not differ in their bromination products.Iodine vapours do not cause cis-trans isomerisation in the solid cis-chalcones.
