N-acyl-2-bromobenzamides participate in metal-halogen exchange with n-BuLi to form N-acyl-%lithiobenzamides, which undergo cyclization to afford 3alkylidenephthalimidines. The pioneering work of Parhaml first demonstrated that certain ortho-substituted aryllithuim reagents 2 can undergo cyclization
The gas-phase interaction energies of methane and neopentane dimers are calculated at various intermolecular distances and geometries using several molecular mechanics and semiempirical parameter sets. For comparisons, a set Ε½ . of reference calculations are also performed using the 6α311G 2 d, 2 p
