1,3 - dimethyl imidazolidine - 2 - ylidene tetra chlorine silicon (iv) as a carbene - transfer - reagent for the representation of carbene - complexes of metals and main group elements by means of movable

摘要

The present invention relates to a new carbene - by means of transmission of reagent, a process for its preparation and its use. It is an object of the invention, it is, the production of carbene - complex, for example from carbene - metal complexes, to simplify the assembly, and, in particular, an alternative to the previous carbene to provide transmission of reagents via. The present invention provides for this purpose - a carbene by means of transmission of the reagent of formula ia # # str3 # # or formula ib # # str4 # # , where r¹, R², R³, R⁴, R⁵ and r⁶ independently of one another are h, substituted or unsubstituted alkyl, cycloalkyl, heteroalk anmeldetextyl, aryl or heteroaryl are. The invention additionally provides a method for its production and use of ready.
