C2-Symmetric nitroxides and their potential as enantioselective oxidants
摘要:
The synthesis and evaluation of four C-2-symmetric nitroxides are presented. The nitroxides were evaluated for their ability to mediate the oxidation of several alcohols and found to have good catalytic activity. One enantioenriched nitroxide was found to kinetically resolve selected secondary alcohols with very modest selectivities. (c) 2005 Elsevier Ltd. All rights reserved.
New naphthalene complexes of Ru(0) with various Ru(η6-naphthalene)(cyclic diene) (3) ligands catalyze linear cross-dimerization between conjugated dienes and acrylates. One of the noteworthy catalysts is the dibenzocyclooctatetraene complex 3d, which shows high catalytic activity for the cross-dimerization between 1,3-pentadiene and methyl acrylate to give the cross-dimers in 99% yield (branch/linear
