Density functional theory (DFT) predicts that bicyclo[3.1.0]hexatriene ( 2) is more stable than its isomer m-benzyne ( 1). Hess [Eur. J. Org. Chem. (2001) 2185] has argued that experimental findings suggesting 1 can equally or even better be associated with 2. However, high level ...

Lu) series by means of density functional theory (DFT) methods disclose that having large concentrations within the temperature interval of fullerene formation, the metal–carbide endohedral fullerenes M2C2@C96 are found to be more stable than the dimetallofullerenes M2@C98. When encapsulating...
The N-9 isomer of 6-chloropurine 13a containing ferrocenylmethylene unit showed a favourable in vitro physicochemical and ADME properties including high solubility, reasonable permeability and good metabolic security in human liver microsomes.This paper experimentally investigates passive personal visible light...
The degree of regiospecific reaction determines the extend to which crude product will be contaminated with the 7,7-disubstituted isomer. Reactions which are greater than 90% directed will occur for the 6,6-disubstituted compounds when the 7-position contains only hydrogen or a small (phenyl or ...
