142087-14-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 142087-14-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,8 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142087-14:
(8*1)+(7*4)+(6*2)+(5*0)+(4*8)+(3*7)+(2*1)+(1*4)=107
107 % 10 = 7
So 142087-14-7 is a valid CAS Registry Number.

A convenient way for alkylation of amines using xanthate esters

Sukrutha, Kodipura P.,Swaroop, Toreshettahally R.,Preetham, Ramesh,Lokanath, Neratur K.,Rangappa, Kanchugarakoppal S.,Sadashiva, Maralinganadoddi P.

, p. 2316 - 2323 (2021)

N-alkylation of amines by the reaction with xanthate esters in the presence of acetic acid catalyst in ethanol is reported. Short reaction time, high yield, general applicability and environmentally benign nature are the noteworthy features of our protocol. The probable mechanism for the formation N-alkylation of amines is proposed.

Synthesis of 1,2,3-Triarylpyrroles from 1-Benzylbenzotriazoles via [1 + 2 + 2] Annulation

Katritzky, Alan R.,Wang, Zouquan,Li, Jianqing,Levell, Julian R.

, p. 1379 - 1381 (1997)

1,2,3-Triarylpyrroles 7 have been synthesized by sequential lithiation and alkylation of 1-benzylbenzotriazoles 1 with 2-bromoacetaldehyde diethyl acetal (2) and N-benzylideneaniline (4), followed by treatment with formic acid in ethanol.

Convenient and stereoselective synthesis of symmetrical (E)-stilbenes via homocoupling of 1,3-dibenzylbenzotriazolium bromides

Xiao, Xiaohui,Lin, Daqin,Tong, Shuitian,Luo, Hong,He, Yinfeng,Mo, Hailan

supporting information; experimental part, p. 1731 - 1734 (2011/09/16)

Using NaH as the base and DMSO as the solvent, a series of symmetric (E)-stilbenes were prepared in good yields via the -homocoupling of 1,3-dibenzylbenzotriazolium bromides at room temperature. Georg Thieme Verlag Stuttgart · New York.
