Benzene reacts (1) with chlorine, to form (a) substitution products (one-half of the chlorine forms hydrogen chloride) such as chlorobenzene, C6H5Cl; dichlorobenzene, C6H4Cl2(1,4) and (1,2); trichlorobenzene, C6H3Cl3(1,2,4); tetrachlorobenzene (1,2,3,5); and (b) addition produc...
doi:10.1016/S0022-1139(00)85311-7The reactions of mixtures of bromine trifluoride and bromine with hexa-, penta- and bromopenta-fluorobenzene, with octafluorotoluene and decafluoro -p-xylene and 2,3,4,5,6-pentafluorotoluene and -anisole have been investigated. The initial products were poly...
Sulphonation of Benzene: Sulphonation of benzene is a process of heating benzene with fuming sulphuric acid (H2SO4+SO3) to produce Benzene sulphuric acid. The reaction is reversible in nature. Halogenation of Benzene: Benzene reacts with halogens in the presence of Lewis acids like FeCl3, FeB...

the activating effect of thecarbonyl groupon the 3-position ofchromanonesandflavanonesensures thathalogenationnormally occurs at that position preferentially. Thus, 3-mono- and 3,3-di-bromination is readily achieved with appropriate molar proportions of bromine butbrominationof 2,3-dihydronaphtho[2,1...
carbon,thus forming a carbonium ion.The carbonium ion further reacted with benzenes to form a complex.Due to unstabilit of the complex,a deuterated ring proton was transferred into an electronegative 1-carbon of the side chain to substitute for the AlCl3,accordingly 2-phenyldodecane was ...
