2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) 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 carbon–bromine bond is electrophilic in nature. 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.Category: bromides-buliding-blocks

1-(Bromoacetyl)pyrene and its arsonium salt as novel photoinitiators for styrene polymerization was written by Mishra, Anuradha;Daswal, Swati. And the article was included in Journal of Applied Polymer Science in 2006.Category: bromides-buliding-blocks The following contents are mentioned in the article:

The photopolymerization of styrene (Sty) in DMSO induced by pyrene (Py), 1-acetylpyrene (AP), 1-(bromoacetyl) pyrene (BP), and 1-acetylpyrene tri-Ph arsonium bromide (APAS) was studied. Under all conditions used, Py was completely ineffective. Incorporation of a chromophoric (COMe) moiety introduces photoinitiating activity into Py. Introduction of Br into AP markedly accelerated the rate of UV irradiation-induced polymerization BP was further modified to its arsonium salt (APAS). The kinetics and mechanism of polymerization using BP and APAS as initiators were investigated in detail. The polymerization with BP followed nonideal kinetics (Rp ∞ [BP]0.8 [Sty]1.1) with respect to initiator concentration whereas ideal kinetics (Rp ∞ [APAS]0.48 [Sty]1.1) was observed when APAS was used as initiator. Degradative transfer is thought to be mainly responsible for this unusual kinetic behavior for the BP-Sty system. The kinetic data proved that BP was a more effective and faster initiator than APAS. In both the cases, the mechanism of polymerization was free radical as evident by the inhibiting effect of hydroquinone and ESR studies. IR and NMR spectra showed the atactic nature of the polystyrene. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Category: bromides-buliding-blocks).
