Allyl bromide

Allyl bromide is an electrophilic alkylating agent. [4] It reacts with nucleophiles, such as amines, carbanions, alkoxides, etc., to introduce the allyl group: . CH 2 =CHCH 2 Br + Nu − → CH 2 =CHCH 2 Nu + Br − (Nu − is a nucleophile). It is used in the synthesis of compounds containing the allyl functionality, such as the pharmaceuticals methohexital, …

Sodium bromide ACS reagent, = 99.0 7647-15-6

A novel aqueous two-phase system (ATPS) only containing Gemini surfactant ethanediyl-1,2-bis(dodecyldimethylammonium bromide) and an inorganic salt sodium bromide was designed, and the physicochemical properties of the ATPS were investigated systematically. The results have shown that the coexisting two phases, one

Iron(II) bromide

Iron(II) bromide refers to inorganic compounds with the chemical formula FeBr 2 (H 2 O) x. The anhydrous compound (x = 0) is a yellow or brownish-colored paramagnetic solid. The tetrahydrate is also known, all being pale colored solids. They are common precursor to other iron compounds.

Silver bromide

Silver bromide (AgBr) is a soft, pale-yellow, water-insoluble salt well known (along with other silver halides) for its unusual sensitivity to light. [6] This property has allowed silver halides to become the basis of modern photographic materials. [7] AgBr is widely used in photographic films and can be found naturally as the mineral bromargyrite. [8]

Elimination by the E2 mechanism

Similarly, groups that favor ionization of the halogen may generate a transition state with substantial positive charge on the alpha-carbon and only a small degree of C–H breaking. For most simple alkyl halides, however, it is proper to envision a balanced transition state, in which there has been an equal and synchronous change in all the bonds.

Lead(II) bromide | Br2Pb | CID 24831

Lead mimics other biologically important metals, such as zinc, calcium, and iron, competing as cofactors for many of their respective enzymatic reactions.For example, lead has been shown to competitively inhibit calcium''s binding of calmodulin, interferring with neurotransmitter release. It exhibits similar competitive inhibition at the NMDA receptor …
