Minimalist N-heterocyclic carbene boranes 1,3-dimethylimidazol-2-ylideneborane and 2,4-dimethyl-1,2,4-triazol-3-ylideneborane are readily available and have low molecular weights. They exhibit superior performance to first-generation NHC−boranes, providing improved yields in reductions of xanthates and related functional groups.
极简主义的N-杂环卡宾硼烷1,3-二甲基咪唑-2-亚基硼烷和2,4-二甲基-1,2,4-三唑-3-亚基硼烷很容易获得,并且分子量低。它们表现出优于第一代NHC-硼烷的性能,在减少黄药和相关官能团方面提供了更高的收率。
