Trichloro-isocyanuric acids

ALKYL IODIDES N-Methyl-N,N -dicydo-hcxylcarbodiimidium chloride. Trichloro-isocyanuric acid. 

In 2009, Iwabuchi et al. accomplished a highly enantioselective organo-catalytic kinetic resolution of various secondary alcohols by using chirally modified 2-azaadamantane A-oxyls as organocatalysts in the presence of trichloro isocyanuric acid (TCCA). The best results were obtained when a-substituted cyclopentanols and cyclohexanols were employed as the substrates with enantioselectivities of up to 99% ee, as shown in Scheme 9.2. 

Oxadiazoles 7 are likewise obtained from hydrazides and aldehydes in the presence of trichloro isocyanuric acid [468].

Organic Derivatives. Although numerous mono-, di-, and trisubstituted organic derivatives of cyanuric and isocyanuric acids appear in the hterature, many are not accessible via cyanuric acid. Cyanuric chloride 2,4,6-trichloro-j -triazine [108-77-0], is generally employed as the intermediate to most cyanurates. Trisubstituted isocyanurates can also be produced by trimerization of either aUphatic or aromatic isocyanates with appropriate catalysts (46) (see Isocyanates, organic). Alkylation of CA generally produces trisubstituted isocyanurates even when a deUberate attempt is made to produce mono- or disubstituted derivatives. There are exceptions, as in the production of mono-2-aminoethyl isocyanurate [18503-66-7] in nearly quantitative yield by reaction of CA and azitidine in DMF (47).

Trichloro- and tribromo-isocyanuric acids have been reported to react with cinnamic acids ArCH=CHC02H in Na0H/H20/Et20 at room temperature to produce ( )-2-halostyrenes ArCH=CHX (X = C1 or Br) regioselectively in 25-95% yield. Electrophilic addition of the halogen atom has been identified as the rate-limiting step by using Hammett correlations and DFT calculations. " ... 

Triazines, formerly symmetric or 5-triazines, have been known for almost 200 years, and are, like many heterocyclic compounds, often referred to by trivial names. Common trivial names used include cyanuric acid (2,4,6-trihydroxy-l,3,5-triazine (1)), cyanurates (2,4,6-trialkoxy-1,3,5-triazines (2)), cyanuryl chloride (2,4,6-trichloro-l,3,5-triazine (3)), isocyanurates (1,3,5-trialkyl-...
