Abstract (en)

[origin: WO2008125568A1] The present invention relates to a process for preparing precursors of carbenes of CAAC type (Cyclic) (Alkyl) (Amino) (Carbenes) and to the use thereof for preparing said carbenes. The invention relates to the use of new synthesis intermediates for preparing the precursors of CAAC-type carbenes. The new production intermediates correspond to the following formula: (I) the various symbols having the meaning given in claim 1. Other subjects of the invention lie in the conversion of the compounds of formula (I) for the purpose of obtaining the CAAC-type carbenes.
