Disclosed are enol ethers compounds. The enol ethers exhibit low volatile organic content and are useful in a variety of chemical applications. The enol ethers can be used in applications as diluents, wetting agents, coalescing aids, paint additives and as intermediates in chemical processes. The enol ethers also have particular utility as film-hardening additives in coating formulations.

rhodium-catalyzed directinggroup promoted selective C–H olefination reaction of indolizines at the 8-position is reported. Di-olefination at 2,8-positions also achieved with silver hexafluoroantimonate as an additive under similar reaction conditions. Weakly coordinating groups, such as ketone, aldehyde, amide and ester, were used as directinggroups. The ester group can be removed under acid conditions

thus put forth RTN4 as a potential novel colorectal cancer therapeutic target and reveal a unique druggable hotspot within RTN4 that can be targeted by covalent ligands to impair colorectal cancer pathogenicity. Our results underscore the utility of coupling the screening of fragment-based covalent ligands with isoTOP-ABPP platforms for mining the proteome for novel druggable nodes that can be targeted
Hydrogen Peroxide Promoted Mizoroki–Heck Reactions of Phenyldiazenes with Acrylates, Acrylamides, and Styrenes

generation of phenyldiazenes from azocarboxylates allowed clean and selective reactions with styrenes, acrylates, and acrylamides using palladium(II) acetate in the presence of silver(I) acetate or hydrogen peroxide as oxidant. Hydrogen peroxide was thereby shown to be a cheap and broadly applicable alternative for the established palladium–silver(I) system.

is disclosed. The process entails (1) reacting an oxidizing agent with a sterically hindered secondary amine to produce an aqueous phase and a nitroxyl radical (2) removing the aqueous phase and adding to the nitroxyl radical one or more vinyl monomer(s) conforming to a formula and a system which produces free radicals. Also disclosed is a process of polymerizing monomers using the functional alkoxyamine.
