Diazotization: react methyl anthranilate with sodium sulfite to variety 2-carbomethoxy benzene-diazonium chloride. Sulfonation & oxidation: then respond with sulfur dioxide and chlorine to produce two-carbomethoxy benzene sulfonyl chloride.
Coulson and Moffitt proposed which the carbon-carbon bonds in cyclopropane rings are bent based on quantum mechanical calculations. This concept of bent bonds is supported by electron density maps from X-ray experiments. Molecular orbital principle explains that the overlap of orbital axes is maximized in cyclohexane, resulting in more powerful carbon-carbon bonds, Whilst in cyclopropane the orbital overlap is fewer, making the bonds weaker and allowing for for ring-opening.
