Flash Communication: Microwave-Assisted Synthesis of 2-Alkylphenyl-Substituted (NHC)CuCl Complexes

Abstract A base-free, microwave-assisted protocol using Cu2O and NHC·HCl salts is reported, which allows the synthesis of sterically less hindered 2-alkylphenyl-substituted (NHC)CuCl complexes, (SIMeortho)CuCl, (SIPrortho)CuCl, (IMeortho)CuCl and (IPrortho)CuCl; the use of dichlo...

Flash Communication:A Lewis Acidity-Diminished, StableDiborylethyne

Abstract The synthesis and reactivity of (dan)BC≡CB(dan), a previously untapped diborylethyne characterized by remarkably diminished Lewis acidity are reported. In contrast to Lewis acidic analogues that decompose upon exposure to water, the dan-substituted diborylethyne exhibits...
