A direct, highly enantioselective alkylation of arylacetic acids via enediolates using a readily available chiral lithium amide as a stereodirecting reagent has been developed. This approach circumvents the traditional attachment and removal of chiral auxiliaries used currently for this type of transformation. The protocol is operationally simple, and the chiral reagent is readily recoverable.

The previously developed TriA-X polyimide resin, consisting of pyromellitic dianhydride/2-phenyl-4,4?-diaminodiphenyl ether; 9,9-bis(4-aminophenyl)fluorene/4-phenylethynylphthalic anhydride (PEPA), was exposed for 3000 h to air at 180, 240, and 270C or a vacuum environment at 270C, in order to study its long-term thermal stability. The weight loss and dimensional changes were measured. Elemental analysis was also conducted in order to estimate the TriA-X degradation process. The TriA-X exhibited excellent thermal stability at 180C and a very small degree of degradation at 240C, with the degradation becoming significant at 270C. The latter was primarily dominated by the oxidation of a chain-extension moiety formed by the cure reaction of the end-cap PEPA.

Recommanded Product: 4265-16-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4265-16-1, in my other articles.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: 4265-16-1, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 4265-16-1, Name is Benzo[b]furan-2-carboxaldehyde, molecular formula is C9H6O2

A simple, high yielding, two-step, one-pot protocol for the preparation of trifluoromethyl-substituted vinylcyclopropanes from alpha-CF3 homoallyl alcohols is disclosed. Destabilization of the cationic intermediate by the electron-withdrawing CF3 group greatly enhances neighboring group participation of the alkene, allowing ring closure to predominate. The reaction can be extended to the difluoromethyl and pentafluoroethyl group, enabling the preparation of a diverse array of fluoroalkyl-substituted vinylcyclopropanes. A diverse array of fluoroalkyl-substituted vinylcyclopropanes are prepared in a simple, high-yielding, two-step, one-pot protocol by means of cationic ring-closure.
