Trichloroacetic acid tert-butyl ester, also known as tert-butyl trichloroacetate, is an organic compound with the chemical formula C4H7Cl3O2. It is a colorless liquid that is soluble in organic solvents and has a molecular weight of 191.46 g/mol. This ester is synthesized by the reaction of trichloroacetic acid with tert-butanol in the presence of a catalyst, such as sulfuric acid. It is primarily used as a reagent in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals. Due to its reactivity, it is important to handle Trichloroacetic acid tert-butyl ester with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.

1860-21-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1860-21-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,6 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1860-21:
(6*1)+(5*8)+(4*6)+(3*0)+(2*2)+(1*1)=75
75 % 10 = 5
So 1860-21-5 is a valid CAS Registry Number.

Reactions of Carbonyl Diisocyanate with Amides and Acids

Akteries, Bernhard,Jochims, Johannes C.

, p. 669 - 682 (2007/10/02)

Carbonyl diisocyanate (1) reacts with primary amides to give 1-acylated isocyanuric acids (5, 6).With secondary amides, 1 affords the rather instable oxadiazinediones 4, which for certain substituents rearrange to give triazines (5, 10).With nucleophiles, compounds 4 give oligourets, e.g. with ureas pentaurets (11, 12) were obtained.Carbonyl diisocyanate reacts with hydrogen halides to afford the crystalline urea-1,3-dicarbonyl halides 13a-c.Diverse products (16, 17, 24, 26) were obtained with carboxylic acids.In most cases oxadiazinediones (26) were isolated, which can be transformed with nucleophiles into acyl ureas 30, 31, biurets 32, and triurets 33.Acetylation of 26 leads to the reactive heterocycles 34.
