302912-34-1 Usage

Uses

1-Ethynyl-2,4-difluorobenzene (CM) may be used to synthesize sulfonatedpoly(aryleneether)s containing CM and TFP [4-[Trifluorovinyl(oxy)]phenol]. It may also be employed for the preparation of 4-(2,4-difluorophenylethynyl)-3-methyl-5-phenylisoxazole.

General Description

1-Ethynyl-2,4-difluorobenzene is an alkyne bearing fluoro group in the phenyl ring.

Check Digit Verification of cas no

The CAS Registry Mumber 302912-34-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,2,9,1 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 302912-34:
(8*3)+(7*0)+(6*2)+(5*9)+(4*1)+(3*2)+(2*3)+(1*4)=101
101 % 10 = 1
So 302912-34-1 is a valid CAS Registry Number.

Synthesis and Photochemical Application of Hydrofluoroolefin (HFO) Based Fluoroalkyl Building Block

Varga, Bálint,Tóth, Balázs L.,Béke, Ferenc,Csenki, János T.,Kotschy, András,Novák, Zoltán

supporting information, p. 4925 - 4929 (2021/07/01)

A novel fluoroalkyl iodide was synthesized on multigram scale from refrigerant gas HFO-1234yf as cheap industrial starting material in a simple, solvent-free, and easily scalable process. We demonstrated its applicability in a metal-free photocatalytic ATRA reaction to synthesize valuable fluoroalkylated vinyl iodides and proved the straightforward transformability of the products in cross-coupling chemistry to obtain conjugated systems.

Terminal alkynes from aldehydes via dehydrohalogenation of (Z)-1-iodo-1-alkenes with TBAF

Beshai, Mira,Dhudshia, Bhartesh,Mills, Ryan,Thadani, Avinash N.

supporting information; experimental part, p. 6794 - 6796 (2009/04/07)

Terminal alkynes were prepared in near quantitative yields via dehydrohalogenation of (Z)-1-iodo-1-alkenes with tetrabutylammonium fluoride (TBAF) under mild conditions. The methodology was expanded to include a one-pot, direct synthesis of terminal alkynes from aldehydes without the necessity of isolating and purifying the intermediate iodoalkene.
