62812-90-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 62812-90-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,8,1 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 62812-90:
(7*6)+(6*2)+(5*8)+(4*1)+(3*2)+(2*9)+(1*0)=122
122 % 10 = 2
So 62812-90-2 is a valid CAS Registry Number.

Na2S2O8-mediated efficient synthesis of isothiocyanates from primary amines in water

Fu, Zhicheng,Yuan, Wenhao,Chen, Ning,Yang, Zhanhui,Xu, Jiaxi

, p. 4484 - 4491 (2018/10/17)

We have developed two green, practical, and efficient procedures, including a one-pot one, to synthesize isothiocyanates from amines and carbon disulfide via desulfurization with sodium persulfate. Water is used as the solvent. Basic conditions are necessary for good chemoselectivity for isothiocyanates. Structurally diverse linear and branched alkyl amines and aryl amines are readily converted to isothiocyanates by the two procedures in satisfactory yields. Halogens, benzylic C-H bonds, methylthio, nitro, ester, alkenyl, electron-rich or -deficient (hetero)aryls, acetylenyl, and even phenolic and alcoholic hydroxyls are well tolerated. The one-pot procedure in water can also be used to realize the preparation of chiral isothiocyanates from chiral amines, and the modification of bioactive structures with free amino groups. In large-scale preparation, simple and practical purification procedures independent of column chromatography are developed.

A one-pot preparation of cyanamide from dithiocarbamate using molecular iodine

Nath, Jayashree,Patel, Bhisma K.,Jamir, Latonglila,Sinha, Upasana Bora,Satyanarayana

supporting information; experimental part, p. 1503 - 1506 (2010/05/18)

An efficient one-pot method for the synthesis of cyanamides from dithiocarbamate salts via a double desulfurization strategy using molecular iodine is disclosed. Dithiocarbamates, by the action of iodine yield isothiocyanates in situ, which on treatment with aqueous NH3 give thioureas. The thioureas so generated undergo further oxidative desulfurization with I2 giving corresponding cyanamides in good yields. Environmental benignity, cost effectiveness and high yields are the important attributes of this one pot procedure. The Royal Society of Chemistry 2009.
