Lipase catalyzed solvent free synthesis of monoacylglycerols in various reaction systems and coupling reaction with pervaporation for in situ water removal
Hexaarylcyclotrisiloxanes were selectively prepared by solvent-free synthesis from diarylsilanediol. These well-known stable compounds were found to undergo palladium-catalyzed cross-coupling reaction with aryl halides in good yields. All of attached aryl groups on silicon atom could be utilized. Furthermore, base-sensitive functionality such as acetyl and nitro groups survived the reaction.
As a distinctive supportable route, the solvent-free synthesis of zeolites not only minimizes the problems of conversional hydrothermal synthesis, but also greatly increases the product yields with advantageous characteristics, such as reduced waste production and a hierarchical pore structure.
