Methyl 1,5-diphenyl- and 5-methyl-1-phenyl-2,3-diazabicyclo[3.1.0]hex-2- ene-6-exo-carboxylates at 138 C undergo decomposition via elimination of nitrogen molecule with formation in each case of five products. Two products are methyl 1,3-diphenyl(or 1-met

A fact of a reversible thermal inversion of exo- and endo-isomers of methyl 1,3-diphenylbicyclo[1.1.0] butane-2-carboxylate was established experimentally. The equilibrium constant of the process at 126°C is 14.2 with endo-isomer prevailing. Using DFT/PBE/L22 method the geometry of the isomers was optimized and also the geometry of the previously studied related exo,exo- and endo,endo-isomers of dimethyl 1,3-diphenylbicyclo[1.1.0] butane-2,4- dicarboxylate. The energy barrier of these mutual conversions was estimated. Pleiades Publishing, Ltd., 2012.
