Isopentyltriphenylphosphonium bromide (cas: 28322-40-9) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.HPLC of Formula: 28322-40-9

Enantioselective Oxidation of Alkenes with Potassium Permanganate Catalyzed by Chiral Dicationic Bisguanidinium was written by Wang, Chao;Zong, Lili;Tan, Choon-Hong. And the article was included in Journal of the American Chemical Society in 2015.HPLC of Formula: 28322-40-9 This article mentions the following:

Chiral anion-controlled ion-pairing catalysis was demonstrated to be a wide-ranging strategy that can utilize a variety of cationic metal species. In a similar manner, we envision a complementary strategy using chiral cation in partnership with inorganic anionic metal salts. Herein, we report a chiral dicationic bisguanidinium-catalyzed asym. oxidation reaction of alkenes with potassium permanganate. Chiral induction is attributed to ion-pairing interaction between chiral cation and enolate anion. The success of the current permanganate oxidation reaction together with mechanistic insights should provide inspiration for expansion to other anionic metal salts and would open up new paradigms for asym. transition metal catalysis, phase-transfer catalysis, and ion-pairing catalysis. Thus, e.g., dihydroxylation of tert-Bu 2-phenylacrylate with KMnO4 in presence of biguanidinium I.2Cl/KI afforded diol II (65% yield, 92% ee). In the experiment, the researchers used many compounds, for example, Isopentyltriphenylphosphonium bromide (cas: 28322-40-9HPLC of Formula: 28322-40-9).
