Abstract: Optimized geometry and the corresponding electronic structure and thermodynamic properties of cyclopropylmethoxychlorocarbene (cpmcc), 3-cyclopropylmethoxy-3- chlorodiazirine and their -N2 and –CO elimination and consequent rearrangement products, cyclopropylmethoxyfluorocarbene (cpmfc), 3-cyclopropylmethoxy-3-fluorodiazirine and its transition state and cyclopropylmethoxyhydrocarbene (cpmhc), 3-cyclopropylmethoxy-3- hydrodiazirine and its transition state have been calculated using ab initio methods DFTB3LYP with 6-311++G** basis set. The effect of substitutions was investigated on thermodynamic properties of conversion of 3-cyclopropylmethoxy-3-chloro (flouro or hydro) diazirine to different products. Also, nuclear magnetic resonance chemical shifts have been calculated for reactant, transition state and product with various substitutions.
