Described are N-heterocyclic carbene complexes of the formula I,
where n is 0 or 1, M is a metal atom containing group, R
1
is selected from hydrogen alkyl, cycloalkyl, heterocycloalkyl, aryl and hetaryl, R
2
is selected from hydrogen, alkyl, cycloalkyl, heterocycloalkyl, aryl and hetaryl, wherein R
1
and R
2
do not both stand for hydrogen.
Furthermore, also described are methods for their preparation and their use as catalysts employed in a C—C, C—O, C—N or C—H bond formation reaction.
描述了公式I的N-杂环卡宾配合物,其中n为0或1,M是含有金属原子的基团,R1从氢烷基、环烷基、杂环烷基、芳基和杂芳基中选择,R2从氢、烷基、环烷基、杂环烷基、芳基和杂芳基中选择,其中R1和R2不能同时代表氢。此外,还描述了它们的制备方法以及它们作为催化剂在C—C、C—O、C—N或C—H键形成反应中的用途。
