Formula: C6H6BrClN2On October 31, 1989 ,《Studies on pyrimidine derivatives. XLI. Palladium-catalyzed cross-coupling reaction of halopyrimidines with aryl- and vinyltributylstannanes》 appeared in Chemical & Pharmaceutical Bulletin. The author of the article were Kondo, Yoshinori; Watanabe, Ryo; Sakamoto, Takao; Yamanaka, Hiroshi. The article conveys some information:
The arylation of 2-, 4-, and 5-halopyrimidines with aryltributylstannanes in the presence of dichlorobis(triphenylphosphine)palladium was investigated with successful results. The reaction can be expanded to the synthesis of 2-, 4-, and 5-vinylpyrimidines with generality. Thus the reaction of pyrimidine I (R = Cl) with R1SnBu3 (R1 = Ph, 2-thienyl, vinyl) gave I (R = R1). After reading the article, we found that the author used 5-Bromo-4-chloro-2,6-dimethylpyrimidine(cas: 69696-35-1Formula: C6H6BrClN2)
5-Bromo-4-chloro-2,6-dimethylpyrimidine(cas: 69696-35-1) is a member of organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. They are generally not present in crude oils and are typically the result of additives, cleaning solutions or chemicals used for oil recovery.Formula: C6H6BrClN2
