Development of 5-silylethynyl-1,3-dioxolan-4-one as a new prochiral template for asymmetric phase-transfer catalysis was written by Hashimoto, Takuya;Fukumoto, Kazuhiro;Abe, Naoyuki;Sakata, Kazuki;Maruoka, Keiji. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2010.Formula: C9H11Br This article mentions the following:
Phase-transfer catalyzed asym. alkylation and Michael addition of 5-silylalkynyl-1,3-dioxolan-4-one were developed as a novel strategy to provide highly modular tertiary α-alkyl-α-hydroxy acids bearing an alkyne moiety. In the experiment, the researchers used many compounds, for example, 2-(Bromomethyl)-1,3-dimethylbenzene (cas: 83902-02-7Formula: C9H11Br).
2-(Bromomethyl)-1,3-dimethylbenzene (cas: 83902-02-7) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbonbromine bond is electrophilic in nature. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Formula: C9H11Br
