1-(diphenylmethyl)-2,4-dimethylbenzene is an organic compound with the molecular formula C21H20. It is a derivative of benzene, featuring a diphenylmethyl group (two phenyl rings attached to a methyl group) at the 1-position and two methyl groups at the 2 and 4 positions. 1-(diphenylmethyl)-2,4-dimethylbenzene is characterized by its symmetrical structure and aromatic properties. It is primarily used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its complex structure, it is often synthesized through multi-step reactions involving the use of catalysts and reagents. The compound is typically obtained as a white crystalline solid and is sensitive to light and air, necessitating proper storage conditions to maintain its stability.

Check Digit Verification of cas no

The CAS Registry Mumber 6944-21-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,4 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6944-21:
(6*6)+(5*9)+(4*4)+(3*4)+(2*2)+(1*1)=114
114 % 10 = 4
So 6944-21-4 is a valid CAS Registry Number.

Benzylation of arenes with benzyl halides synergistically promoted by in situ generated superacid boron trifluoride monohydrate and tetrahaloboric acid

Huang, Ruofeng,Zhang, Xiaohui,Pan, Jing,Li, Jiaqiang,Shen, Hang,Ling, Xuege,Xiong, Yan

supporting information, p. 1540 - 1546 (2015/03/04)

To examine the assembly methodology of diarylmethanes, a benzylation of (hetero)arenes with benzyl halides has been developed and various diarylmethanes were furnished with yields of up to 98% and regioselectivities of up to >99%. The complexation of the by-product halogen hydride with BF3·OEt2 generated the Bronsted acid BF3·HX (HBF3X, X=Cl or Br) in situ to synergistically promote the benzylation.

Benzylation of arenes with benzyl ethers promoted by the in situ prepared superacid BF3-H2O

Li, Yu,Xiong, Yan,Li, Xueming,Ling, Xuege,Huang, Ruofeng,Zhang, Xiaohui,Yang, Jianchun

, p. 2976 - 2981 (2014/06/10)

An efficient and environmentally friendly benzylation of arenes with benzyl ethers as benzyl donors using BF3-Et2O to generate in situ the superacid BF3-H2O as an efficient promotor has been described. A wide variety of functional groups have been investigated and found to be compatible to give the desired diarylmethanes in yields of up to 99%. The crucial role of the moisture content in this transformation has been demonstrated by detailed investigations. This journal is the Partner Organisations 2014.
