Dichloromethane as an Unusual Methylene Equivalent. A New Entry of Highly Nucleophilic and Selective Titanium−Methylene Complexes for Ester Methylenation
摘要:
The successful application of CH2Cl2-Mg-TiCl4-system mediated methylenation of various esters such as tert-butyl ester and 2,5-cyclohexadiene-1-carboxylate highlights the extraordinary reactivity, selectivity, and the nonbasic nature of this new methylene-carbenoid, which serves as a practical reagent applicable to large-scale synthesis.
