Oge, Aytek,Mavis, Murat Emrah,Yolacan, Cigdem,Aydogan, Feray
, p. 137 - 146 (2012)
Long chain dicationic ammonium salts (1a-1c), easily prepared from tert-amines and dihaloalkanes, were successfully used as efficient phase-transfer catalysts in the Michael addition reaction of various active methylene compounds to 2-cyclohexenone withou

Conjugate addition reactions of 2,4-pentandione, dibenzoylmethane and ethylacetoacetate to enones have been investigated using Amberlyst-15 or Amberlyst-15-DMAP acetate system as catalysts. When 2,4-pentandione reactions were carried out in the presence o
Heterobimetallic Pd-Sn catalysis: Michael addition reaction with C-, N-, O-, and S-nucleophiles and in situ diagnostics
Das, Debjit,Pratihar, Sanjay,Roy, Sujit
, p. 2430 - 2442 (2013/04/23)
An efficient Michael addition reaction of differently substituted enones with carbon, sulfur, oxygen, and nitrogen nucleophiles has been achieved by a new heterobimetallic "Pd-Sn" catalyst system. The nature of the catalytically relevant species and their
Ionic liquids made with dimethyl carbonate: Solvents as well as boosted basic catalysts for the michael reaction
Fabris, Massimo,Lucchini, Vittorio,Noe, Marco,Perosa, Alvise,Selva, Maurizio
experimental part, p. 12273 - 12282 (2010/06/11)
This article describes 1) a methodology for the green synthesis of a class of methylammonium and methylphosphonium ionic liquids (ILs), 2) how to tune their acid-base properties by anion exchange, 3) complete neat-phase NMR spectroscopic characterisation
Synthesis and evaluation of guanidinyl pyrrolidines as bifunctional catalysts for enantioselective conjugate additions to cyclic enones
Pansare, Sunil V.,Lingampally, Rajinikanth
supporting information; experimental part, p. 319 - 324 (2009/03/12)
Guanidinyl pyrrolidines derived from 'S'-proline are effective catalysts for the enantioselective conjugate addition of malonate, nitroalkane and other carbon and heteroatom nucleophiles to cyclohexenone and cyclopentenone in the absence of basic additive
