Ethenyl-difluoro-borane, also known as vinyldifluoroborane or vinylboron difluoride, is an organoborane compound with the chemical formula C2H3BF2. It is a colorless, volatile, and highly reactive liquid that is sensitive to air and moisture. ethenyl-difluoro-borane is formed by the reaction of acetylene with boron trifluoride, resulting in a molecule that contains a vinyl group (C=CH2) bonded to a boron atom, which is further coordinated by two fluorine atoms. Ethenyl-difluoro-borane is an important reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and the functionalization of alkenes. Due to its high reactivity, it is typically handled under an inert atmosphere and used in controlled reactions to avoid unwanted side products.

358-95-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 358-95-2 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, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 358-95:
(5*3)+(4*5)+(3*8)+(2*9)+(1*5)=82
82 % 10 = 2
So 358-95-2 is a valid CAS Registry Number.

Gas-phase measurements of the kinetics of BF2(+)-induced polymerization of olefinic monomers

Forte, Leonard,Lien, Min H.,Hopkinson, Alan C.,Bohme, Diethard K.

, p. 1576 - 1583 (2007/10/02)

The initial steps in the BF2(+)-induced polymerization of the monomers of ethylene, propylene, cis-2-butene, isobutene, and styrene have been observed in the gas phase at room temperature using the Selected-Ion Flow Tube (SIFT) technique.Rate constants and product distributions have been determined for the initiation of the polymerization in each case.All five initiation reactions were found to be rapid (k >/= 5.0*10-10 cm3 molecule-1 s-1).The primary product ions that propagate polymerization have been identified and sequential addition reactions have been followed in all five systems.For ethylene the energetics of the initial steps have been followed using ab initio molecular orbital theory.Reaction of BF2+ with the vapours of water and benzene have also been characterized. Key words: ion-induced polymerization; alkenes; kinetics; gas phase ion chemistry
