Abstract: A process for preparing acylfluorides by reaction of carbonyl fluoride COF2 with compounds having general formula: T=CR1R2??(I) wherein: T is O or CF2 R1 and R2, equal or different, are F or a R(O)t radical, wherein R=linear or branched C1–C7 (per)fluoroalkyl, optionally containing one or more oxygen atoms, t is an integer equal to zero or 1; wherein a catalyst supported on porous compound is used, the catalyst being selected from: CsF, RbF, KF, AgF, each optionally in admixture with one or more of the others.

Abstract: A method for administering pyruvate is disclosed which comprises administering a therapeutically effective amount of a pyruvate precursor to a mammal in the form of pyruvamide or a pyruvyl-amino acid. The pyruvyl-amino acid is preferably selected from the group comprising pyruvyl-glycine, pyruvyl-alanine, pyruvyl-leucine, pyruvyl-valine, pyruvyl-isoleucine, pyruvyl-phenylalanine, pyruvyl-proline and pyruvyl-sarcosine, and their amides and esters as well as their salts. Associated with the administration of a pyruvate precursor to a mammal in accordance with this invention are improved insulin resistance, lower fasting insulin levels, and reduced fat gain. Novel methods of synthesizing several pyruvate precursors are also disclosed.
Abstract: A polymer comprising a carbon-carbon backbone chain and at least one N-(substituted oxalyl)carbamoyl group of the formula: --CO--NH--CO--CO--OR wherein R is a hydrocarbon group as a side chain attached to said backbone chain.
Abstract: The invention is concerned with a process for preparing a C.sub.6 to C.sub.24 fatty acid halide by reacting a fatty acid with a halogenating agent, such as phosphorus trichloride, optionally followed by hydrolysis of unreacted halogenating agent separating and removing an inorganic lower layer to leave a turbid layer containing the fatty acid chloride product. The clearing time of the turbid layer is reduced by the addition of from 3 to 20% by weight of clear fatty acid halide thereto.
