In chemistry, hexahydro-1,3,5-triazine is a class of heterocyclic compounds with the formula (CH 2 NR) 3. Known as aldehyde ammonias, these compounds characteristically crystallize with water . They are reduced derivatives of 1,3,5- triazine , which have the formula (CHN) 3 , a family of aromatic heterocycles.
A trimethylsilyl group (abbreviated TMS) is a functional group in organic chemistry.This group consists of three methyl groups bonded to a silicon atom [−Si(CH 3) 3], which is in turn bonded to the rest of a molecule.
Trimethylsilanol is a weak acid with a pK a value of 11. [10] The acidity is comparable to that of orthosilicic acid, but much higher than the one of alcohols like tert-butanol (pK a 19 [10]). Deprotonation with sodium hydroxide gives sodium trimethylsiloxide. TMS reacts with the silanol groups (R 3 SiOH) giving silyl ethers.
