A mild and neutral reducing system consisting of AlNiCl2.6H2OTHF has been developed and reacted with a series of organic compounds containing different functional groups in order to evaluate its synthetic utility. It was observed that this system very efficiently reduces the α-enones to the saturated ketones, aromatic aldehydes and ketones to the corresponding alcohols, nitriles and nitroarenes to

have been irradiated in the isotropic, smectic B, and two solidphases of n-butyl stearate (BS). The lengths of the ketones were varied from 11 to 31 carbons. The ratios of elimination/cyclization products and diastereomeric cyclobutanol products were measured for each as a function of temperature and BS phase. The effect of 1 and 2 on the phase transition temperatures of BS has been correlated with changes

Glycerine derivatives represented by formula (1A), (2A) and (3A):
wherein R1a, R2a, R1b, R2b, R1c, and R2c are as defined in the disclosure, and process for producing glycerin derivatives, including the glycerin derivatives (1A), (2A) and (3A), are disclosed. The glycerin derivatives have satisfactory physical properties and are applicable as lubricants or polar oils and also have mutual effects with water and are applicable as emulsifying agents or moisture retaining agents. The process makes it possible to synthesize glycerin derivatives from easily and economically available aldehydes or ketones in high yields.
Abstract A facile two-step synthesis of methylketones from alkyl nitriles via the Blaise conversion of nitriles into β-keto esters and acid-mediated hydrolysis followed by decarboxylation of the resulting β-keto esters is described.
