358-21-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 358-21-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 358-21:
(5*3)+(4*5)+(3*8)+(2*2)+(1*1)=64
64 % 10 = 4
So 358-21-4 is a valid CAS Registry Number.

Method for preparing fluorine-containing ether

-

Paragraph 0092-0093, (2019/07/29)

The invention relates to a 'method for preparing fluorine-containing ether', and belongs to the field of chemical synthesis. The method comprises the steps that under a nitrile solvent condition, carbonyl fluoride, trifluoroacetyl fluoride, pentafluoropropionyl fluoride, heptafluoro-n-butyryl fluoride, heptafluoro-iso-butyryl fluoride and other acyl fluorides are taken as raw materials to have anaddition reaction with metal fluorides to obtain perfluoroalkoxide, then under water catalysis, the perfluoroalkoxide and a low-toxic or even non-toxic harmless alkylating agent are subjected to an alkylation reaction to obtain the fluorine-containing ether. The method for preparing the fluorine-containing ether has the advantages that not only is the reaction condition mild, the yield of the fluorine-containing ether is high, but also the low-toxic or even non-toxic harmless alkylating agent is taken as a safe alkylation agent, the process is safe and reliable, and effective separation can beperformed by an ordinary distillation means in the industry.

Electrochemical fluorination of (N,N-dialkylamino)alcohols

Abe, Takashi,Fukaya, Haruhiko,Hayashi, Eiji,Ono, Taizo,Nishida, Masakazu,Soloshonok, Irina,Okuhara, Kunio

, p. 229 - 237 (2007/10/03)

Series of amino alcohols including 2-(N,N-dialkylamino)ethanols, 3-(N,N-dimethylamino)propanol and 4-(N,N-dimethylamino)butanol were subjected to electrochemical fluorination. In the case of 2-(N,N-dialkylamino)ethanols, the F-(2-N,N-dialkylamino)acetyl fluorides were obtained in fair to good yields. Yields of each target compound were strongly dependent on the kind of the dialkylamino group. Cyclic amines having an N-(2-hydroxylethyl) group afforded the corresponding F-[N-(c-alkylamino)-substituted acetyl fluorides]. Their yields were generally better than those of acyclic analogs. Several 2-(N,N-dialkylamino)ethanols and 3-(N,N-dimethylamino)propanol were converted into the corresponding trimethylsilylethers, aminoalkyl methyl carbonates and bis-aminoalkyl carbonate, respectively, and they were subjected to fluorination for a comparison of the yield with that obtained from that of the parent aminoalcohol.

The electrochemical fluorination of N-containing carboxylic acids (Part 4). Fluorination of methyl 3-dialkylamino-isobutyrates and methyl 3-dialkylamino-n-butyrates

Abe, Takashi,Fukaya, Haruhiko,Hayashi, Eiji,Hayakawa, Yoshio,Nishida, Masakazu,Baba, Hajime

, p. 193 - 202 (2007/10/02)

Several methyl esters of 3-dialkylamino-substituted n- and isobutyric acids have been subjected to electrochemical fluorination to give the corresponding perfluoroacid fluorides.Dimethyl, diethyl, pyrrolidino, morpholino, piperidino and N-methylpiperazino groups were investigated as dialkylamino substituents.The structure/yield relationship was evaluated both in terms of the structure of the acid and the kind of amino group, respectively.Better yields of perfluoroacid fluorides were obtained from methyl esters having isobutyric acid skeletons than those having n-butyric acid groups, and from the acids containing cyclic amino groups than those containing acyclic ones.
