Abstract:
(Benzenesulfonyl)difluoromethyl anion, in situ generated from difluoromethyl phenyl sulfone and a base, was found to easily undergo nucleophilic substitution reactions (SN2) with primary alkyl halides, elemental halogens, and perfluoroalkyl halides with good selectivity. The formed (benzenesufonyl)difluoromethylalkanes are useful intermediates for the facile preparation of 1,1-difluoro-1-alkenes and difluoromethylalkanes. Thus, difluoromethyl phenyl sulfone acts as both “CF2═” and “CF2H−” synthons

Abstract:
A device including an active mirror made of thin disk active medium having a pump surface and a mirror surface, means for cooling that contacts with the mirror surface of the active medium dissipating heat from said laser medium, pump beam illuminating the pump surface of said active mirror and a multi-reflection optical system wherein the pump beam is imaged numerous times with the beam structure substantially unchanged during imaging leading to sufficient absorption of the pump beam by said thin disk active medium.
