- AN EXPERIMENTAL STUDY OF SOME NMR METHODS FOR THE MEASUREMENT OF SLOW EXCHANGE RATES
-
The rate of interconversion of the cis and trans rotational isomers of N-triflouroacetyl-N-methylbenzylamine have been determined by a variety of NMR lineshape experiments and by several double resonance methods.Comparison of the results for the slow exch

- Electrochemical approach to trifluoroacetamide synthesis from 1,1,1-trichloro-2,2,2-trifluoroethane (CFC-113a) catalyzed by B12complex
-
One-pot synthetic approach to produce trifluoroacetamide has been developed using an electrochemical method with the B12 complex as a catalyst under mild conditions, in open air at room temperature. Thirty examples of trifluoroacetamide were synthesized from 1,1,1-trichloro-2,2,2-trifluoroethane (CFC-113a) in moderate to good yields. This user-friendly strategy is compatible with a broad range of trifluoroacetamide syntheses.

- Fabrication of asymmetric molecular junctions by the oriented assembly of dithiocarbamate rectifiers
-
The oriented assembly of molecules on metals is a requirement for rectification in planar metal-molecule-metal junctions. Here, we demonstrate how the difference in adsorption kinetics between dithiocarbamate and thioacetate anchor groups can be utilized

- THIENOPYRIMIDONE COMPOUND
-
The present invention relates to a compound represented by the formula: wherein Ar is an optionally substituted ring; A is a spacer having a main chain of 1 to 4 atoms; B is a bond, a C1-10 alkylene group or an oxygen atom; R3 and R5 are each independently a hydrogen atom or a substituent; R4 is an optionally substituted cyclic group or an optionally substituted C1-10 alkyl group; and R1 and R2 are each independently a hydrogen atom or a substituent, or R1 and R2 or R1 and B are bonded to form an optionally substituted nitrogen-containing heterocycle, or R1 and Ar are bonded to form an optionally substituted nitrogen-containing fused heterocycle, or a salt thereof. The thienopyrimidone compound of the present invention has a superior melanin-concentrating hormone receptor antagonistic action, and is useful as an agent for the prophylaxis or treatment of obesity and the like.

- A CONVENIENT SYNTHESIS OF N-ALKYL AND N,N-DIALKYLTRIFLUOROACETAMIDES IN A SOLID-LIQUID TWO-PHASE SYSTEM IN THE PRESENCE OF PHASE-TRANSFER CATALYSTS
-
Trifluoroacetamide is easily monoalkylated in a K2CO3-organic solvent solid-liquid two-phase system affording in good to excellent yields N-alkyltrifluoroacetamides.Under the same conditions, the latter, in turn, ract with alkylating agents giving N,N-dialkyltrifluoroacetamides in high yields.
