• ammonium
  • For example, ammonium carbamate is generated by treatment of ammonia with carbon dioxide 2 NH3 + CO2 → NH4[H2NCOCarbamates also arise via hydrolysis of chloroformamides and subsequent esterification: R2NC(O)Cl + H2O → R2NCO2H + HCl Carbamates may be formed from the Curtius rearrangement, where isocyanates formed are reacted with an alcohol. (wikipedia.org)
  • RNCO + R′OH → RNHCO2R′ Although most of this article concerns organic carbamates, the inorganic salt ammonium carbamate is produced on a large scale as an intermediate in the production of the commodity chemical urea from ammonia and carbon dioxide. (wikipedia.org)
  • These inhibitors include compounds with different functional groups (carbamate, quaternary or tertiary ammonium group), and have been applied in the diagnostic and/or treatment of various diseases such as: myasthenia gravis, AD, post-operative ileus, bladder distention, glaucoma, as well as antidote to anticholinergic overdose.

  • phosgene
  • Rather than reacting with additional alcohol, they may disproportionate to give the desired carbonate diesters and one equivalent of phosgene: PhOH + COCl2 → PhOCOCl + HCl 2 PhOCOCl → PhOCO2Ph + COCl2 With an appropriate catalyst, alcohols can react with carbon monoxide and an oxidant (e.g. oxygen gas).

  • acid
  • A carbamate is an organic compound derived from carbamic acid (NH2COOH). (wikipedia.org)
  • Using the inexpensive Lewis acid magnesium bromide diethyl etherate (commonly prepared fresh by the addition of magnesium turnings to 1,2-dibromoethane in benzene:diethyl ether), the epoxide is opened with allyl amine to yield the corresponding 1,2-amino alcohol. (wikipedia.org)
  • R2NC
  • A related but more useful reaction if the analogous reaction with alcohols: R2NCOCl + R'OH + C5H5N → R2NC(O)OR' + C5H5NHCl Peter Jäger, Costin N.

  • 16. The method of claim 12, wherein the second polymer is propagated at the carbamate linkage by at least one of controlled radical or ring opening polymerization (ROP). (patentsencyclopedia.com)
  • primary
  • 2-CFNA has been shown to be a superior CDA than Mosher's agent to determine the enantiomeric excess of a primary alcohol. (wikipedia.org)
  • important
  • Perhaps the most important carbamate is the one involved in the capture of CO2 by plants since this process is necessary for their growth. (wikipedia.org)
  • The findings concerning neural mechanisms underlying cognitive function and addiction help direct the behavioral toxicology and therapeutic development studies, while the applied studies provide important functional information concerning the importance of the basic mechanisms under investigation.

  • known
  • Excessive quantities of GCA can also be hazardous to health[citation needed], tobacco smoke, most barbiturates, and some carbamates are known to actually stimulate GCA production. (wikipedia.org)
  • This approach focuses on grouping chemical and functional responses in a manner so that individual chemicals with known modes of action can be separated into specific FATS. (wikipedia.org)
