N-Heterocyclic carbene-induced transmethylation in tungsten imido alkylidene bistriflates: Unexpected formation of an N-heterocyclic olefin complex
Imbrich, Dominik A.,Frey, Wolfgang,Buchmeiser, Michael R.
, p. 12036 - 12039 (2017)
The reaction of [W(N-2,6-iPr2C6H3)(CHCMe2Ph)(OTf)2(DME)] (DME = 1,2-dimethoxyethane, OTf = CF3SO3) with the N-heterocyclic carbene (NHC) 1,3-bis(2,4,6-trimethylphenyl)imidazolidin-2-ylidene (IMesH2) leads to DME activation followed by transmethylation and in due consequence to the formation of the N-heterocyclic olefin complex [W(N-2,6-iPr2C6H3)(CHCMe2Ph)(OTf)2(IMesH2CH2)] along with [W(N-2,6-iPr2C6H3)(CHCMe2Ph)(OTf)(IMesH2)(κ2-O(CH2)2OMe)], [1,3-bis(2,4,6-trimethylphenyl)-2-methylimidazolidinium+ (OTf-)] and [1,3-bis(2,4,6-trimethylphenyl)-2-H-imidazolidinium+ (OTf-)]. A reaction pathway is proposed and confirmed by the use of 13C-labelled compounds; structures of the products were verified by NMR and/or single-crystal X-ray analysis.
Continuous synthesis and use of N-heterocyclic carbene copper(I) complexes from insoluble Cu2O
Opalka, Suzanne M.,Park, Jin Kyoon,Longstreet, Ashley R.,McQuade, D. Tyler
supporting information, p. 996 - 999 (2013/04/10)
It is demonstrated that homogeneous N-heterocyclic carbene-copper(I)- chloride complexes can be prepared continuously by flowing NHC precursors through a packed bed of solid Cu2O suspended in molecular sieves. The method enables the synthesis o
An efficient synthesis of imidazolinium salts using vinyl sulfonium salts
McGarrigle, Eoghan M.,Fritz, Sven P.,Favereau, Ludovic,Yar, Muhammad,Aggarwal, Varinder K.
, p. 3060 - 3063 (2011/07/31)
The synthesis of imidazolinium salts from the reaction of formamidines and (2-bromoethyl)diphenylsulfonium triflate is described. A variety of symmetrical and unsymmetrical imidazolinium triflate salts were synthesized in high yield in short reaction time
