Abstract: Imidazolium-benzimidazolates are readily available conjugated mesomeric betaines, whose carbenic tautomers can form C,Nimine-metal chelates containing amino-functionalised normal or abnormal NHC ligands, depending on the degree of steric congestion. Deprotonation of the amino moiety gives rise… read more here.

Abstract: The compounds [tBu3PCO2B(C6F5)3] 1 and [TMPH][C5H6Me4NCO2B(C6F5)3] 7 are easily handled synthons releasing CO2 on warming generating the corresponding FLPs which can activate H2, disulfides, alkynes, silanes and phenols. Compound 7 was also shown to be… read more here.
