1,2-bis(trifluoromethyl)-3,3,4,4-tetrafluorocyclobutene is a cyclic organic compound characterized by its unique molecular structure. It consists of a four-membered carbon ring with two trifluoromethyl groups attached to the 1 and 2 positions, and two tetrafluoro groups at the 3 and 4 positions. 1,2-bis(trifluoromethyl)-3,3,4,4-tetrafluorocyclobutene is known for its stability and chemical inertness, which makes it a valuable intermediate in the synthesis of various fluorinated compounds. Due to its highly fluorinated nature, it exhibits interesting properties such as low reactivity and high thermal stability, which are desirable in applications like pharmaceuticals, agrochemicals, and materials science. The compound's structure also contributes to its potential use in the development of new materials with unique properties, such as improved heat resistance or chemical resistance.

Check Digit Verification of cas no

The CAS Registry Mumber 719-27-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 719-27:
(5*7)+(4*1)+(3*9)+(2*2)+(1*7)=77
77 % 10 = 7
So 719-27-7 is a valid CAS Registry Number.

Reactions involving Fluoride Ion. Part 23. Thermolytic Defluorination of Perfluoroalkenes in the Synthesis of Fluorinated Dienes and Cyclobutenes

Chambers, Richard D.,Lindley, Andrew A.,Fielding, Harold C.,Moilliet, John S.,Whittaker, Graham

, p. 1064 - 1067 (1981)

Passage of perfluoro-3,4-dimethylhex-3-ene over iron or platinum at elevated temperatures leads to defluorination and fragmentation, giving fluorinated dienes, e.g. perfluoro-2,3-dimethylbutadiene (over Pt) and perfluoro-3,4-dimethylhexa-2,4-diene (over Fe), together with other products.Similar reactions with other fluorinated alkenes and the variation between fragmentation and fluorination is rationalised on the basis of the metal used, etc.The fluoride induced reaction between perfluoropropene and perfluorobut-2-ene gives perfluoro-2,3-dimethylpent-2-ene.
