General description

Thermodynamics of formation of inclusion complex between 2-chlorobenzophenone and cyclomaltoheptaose (β-cyclodextrin) has been investigated by UV-vis spectroscopy and reversed-phase liquid chromatography. 2-Chlorobenzophenone undergoes reduction in the presence of LiAlH4 and (R)-(-)-2-(2-iso-indolinyl)butan-1-ol to afford the corresponding benzhydrols.

Application

2-Chlorobenzophenone was used in the synthesis of 1-(2-chlorophenyl)isoquinolin-3-yl trifluoromethanesulfonate.

A thermodynamic study of the inclusion process between 2-chlorobenzophenone (2ClBP) and cyclomaltoheptaose (β-cyclodextrin, β-CD) was performed using UV-vis spectroscopy, reversed-phase liquid chromatography (RP-HPLC), and molecular modeling (PM6). Spectrophotometric measurements in aqueous solutions were performed at different temperatures. The stoichiometry of
