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...

H‐Likelihood Approach on the Joint Frailty Model for Clustered Bivariate Survival Data

ABSTRACT Recently, clustered bivariate survival data have been extensively studied using different modeling approaches, such as frailty models and copula models. These data can take several forms, including bivariate censored data, semicompeting risks data, and competing risks da...

Multivariate Spatio-Temporal Modeling for Regional GIS Data: A Statistical Framework for Analyzing Multidimensional Spatial Interactions

Abstract. Open geospatial datasets increasingly contain multiple regional indicators that evolve jointly across space and time, but applied workflows often fit separate regressions for each indicator and communicate results through static choropleth maps. We present an open-sourc...

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...
