Aminoalkylbenzotriazoles: reagents for the aminoalkylation of electron rich heterocycles
摘要:
Secondary and tertiary aminoalkylbenzotriazoles react with pyrrole, indole, their N-methyl analogs and with 2-methylfuran under mild reaction conditions in the presence of a Lewis acid to afford selectively the corresponding secondary or tertiary amines.

The refrigerating machine oil composition of the present invention contains a polyol ester as a base oil, a phosphorothionate, a phosphorus-based additive other than said phosphorothionate, and a glycidyl ester epoxy compound. With the refrigerating machine oil composition of the present invention, a high level can be attained for both lubricity and stability in a refrigerating/air conditioning apparatus in which an HFC refrigerant or the like is used, and the refrigerating or air-conditioning apparatus can be stably operated over an extended period.

The refrigerating machine oil of the present invention contains a mineral oil whose nitrogen content is not more than 50 ppm by mass and whose percent in aromatic ring structures (% C
A
) is from 5 to 25. With the refrigerating machine oil of the present invention, high levels of lubricity, stability, and miscibility with refrigerants are attained, with a good balance between these, so refrigerating and air conditioning machines can be operated stably over a longer period.
