89089-14-5 Usage

Uses

Electrophilic chlorinating reagent, particully effective for the chlorination of bithiophenes

Check Digit Verification of cas no

The CAS Registry Mumber 89089-14-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,8 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 89089-14:
(7*8)+(6*9)+(5*0)+(4*8)+(3*9)+(2*1)+(1*4)=175
175 % 10 = 5
So 89089-14-5 is a valid CAS Registry Number.

Conversion of nucleophilic halides to electrophilic halides: Efficient and selective halogenation of azinones, amides, and carbonyl compounds using metal halide/lead tetraacetate

Kim, Jeum-Jong,Kweon, Deok-Heon,Cho, Su-Dong,Kim, Ho-Kyun,Lee, Sang-Gyeong,Yoon, Yong-Jin

, p. 194 - 200 (2007/10/03)

AlCl3/Pb(OAc)4 and ZnBr2/Pb(OAc) 4 are efficient electrophilic N- and α-C-halogenating agents. A variety of azinones, amides and carbonyl compounds were chemoselectively and regioselectively N-, or α-C-halogenated in good to excellent yield using AlCl3/Pb(OAc)4 and ZnBr2/Pb(OAc)4 in acetonitrile.

2-Chloropyridazin-3(2H)-ones as electrophilic chlorinating agents: Effective α-chlorination of active methylene/methine compounds

Park, Yong-Dae,Kim, Jeum-Jong,Cho, Su-Dong,Lee, Sang-Gyeong,Falck, J. Russell,Yoon, Yong-Jin

, p. 1136 - 1140 (2007/10/03)

2,4,5-Trichloro- (2a) and 2,4-dichloro-5-methoxypyridazin-3(2H)-one (2b) are novel electrophilic chlorinating agents. α-Chlorination of active methylene/methine compounds with 2 in the presence of either Lewis or protonic acids in dichloromethane (for Lewis acid) or water (for protonic acid or none) at room temperature gave also selectively α-monochlorides and/or α,α-dichlorides in good to excellent yields.
