toxicity, air stability, and low volatility. It was used as a synthetic precursor in the preparation of a variety of arsenic(III) derivatives like arsines, arsenites, and thioarsenites. Besides that, AsI3 was submitted to a diversity-oriented Grignard reaction in the preparation of a homologous series of trialkyl arsines ranging from AsC3H9 to AsC12H27. The series was analyzed by comprehensive two-dimensional

standard molar enthalpy of formation of arsenic alkoxides in the liquid phase, As(OR)3R = ethyl (Et),n-propyl (Prn),i-propyl (Pri),n-butyl (Bun) andi-butyl (Bui)}, was determined through reaction-solution calorimetry in chloroform based on the reaction: As(NEt2)3(1) + 3ROH(1) = As(OR)3(1); ΔsolHmoatT= 298.15 K. This series of alkoxides gave the following molar enthalpy of formation ΔfHmovalues: −(758
