CO2-selective Absorption Using m-Xylylenediamine

Inagaki and Mukai et al. have reported the CO2-selective capturing function of m-xylylenediamine (MXDA) from the air. According to their report, by putting MXDA on a petri dish and stored in the air, CO2 in air is smoothly captured as a MXDA・CO2 adduct (1) by reacting with an amino group of MXDA. The adduct 1 keeps capturing CO2 without undergoing a moisture mediated hydrolysis because 1 has the hydrophobic phenyl group effectively preventing hydration. On the other hand, 1 generates dry CO2 by heating and the formed CO2 is directly applied to Grignard reactions since it is without moisture. In the technique of CO2 capture and storage (= CCS), CCS generally absorbs CO2 with water contamination, requiring higher heating conditions to generate CO2 gas. Therefore, this technology is expected to be used for performing non-moisture capturing CCS.

MAC-TBS Reagent Usable for Three Component Coupling Reactions

(tert-Butyldimethylsilyloxy)malononitrile (1), developed by Nemoto et al., is called a MAC (Masked Acyl Cyanide) reagent.1) 1 forms an anion species 2 by the treatment of a base and 2 acts as an acyl anion equivalent. By taking advantage of this property, 1 can be applied to three component coupling reactions with electrophiles and nucleophiles.2,3) For example, 2 reacts with aldehydes to form an acyl cyanide intermediate 3. Sequential addition of amines as nucleophiles gives α-siloxyamides as three component adducts.3) In these sequential steps, three components can be added in one-portion to the flask. This reaction can be applied to electrophiles such as aldehydes, ketones and imines and nucleophiles such as alcohols and amines. Furthermore, this reaction can afford Weinreb amides when using DMHA·HCl.
