In order to stabilize carboxylic acid and ester molecules in a monomeric state for spectroscopic investigation, solid inclusion formation experiments have been carried out with the 2,2′-bis(hydroxydiphenylmethyl)-1,1′-biphenyl host molecule (1) a

Most organic reactions have long been carried out in organic solvents without concern for their real necessity, reaction efficiency, and pollution problems. Very recently, we have found that most organic reactions can be carried out in the absence of

Solvent-free Rap–Stoermer reactions were found to very efficiently give products in almost quantitative yield by just washing the reaction mixture with water. The reaction mechanism has been clarified completely by continuous IR spectral monitoring

As found using FTIR, powder diffraction and CD spectrometry, in reversible inclusion complexation between crystalline hosts and gaseous guests, host molecules showed novel chiral switching phenomena: fast and reversible molecular displacement, rotati
