Classify each of these elements as representative, transition, or inner transition; state whether each is a metal or a nonmetal; and give its normal phase: (a) nickel (b) magnesium (c) bromineAt first, the periodic table placed the elements...
detection limits and without chloride interferences, but involve multistep reactions containing removal of free bromide [52] or suf- fer from interference in chlorinated waters [53]. A previous our work [54] showed that the bromine formed from bromate with acidic conditions reacted with 2,6-di...

a benzylic hydrogen of toluene is 3.3 times as reactive toward bromine atoms as the tertiary hydrogen of an alkane and nearly 100 million times as reactive as a hydrogen of methane. In the presence of a potassium catalyst dispersed on calcium oxide, toluene reacts with 1,3-butadiene to yield...
The starting compound (II) can be produced, for example, by reacting a compound of the formula: ##STR7## [wherein all the symbols have the meanings defined hereinbefore] with a compound of the formula: ##STR8## [wherein Z is halogen such as chlorine, bromine or iodine, and Y has ...
The compound 1-(α-ethyl-α-methyl-succinimido)-2-chloro-5-sulphamoylbenzene is described and claimed in my above mentioned U.S. Pat. No. 3,574,194 and as such is not included within the scope of the present invention. R5is either a halogen atom such as bromine, or more preferably...
Compounds of formula I, wherein R4is other than hydrogen, are obtained by treatment of the compound of formula I wherein R4is hydrogen, obtained as just described, with the halide R4-hal, wherein hal is a halogen, preferably chlorine or bromine, and R4has the meaning defined above, in ...
Although the halogen atom among them may be chlorine, bromine or iodine, chlorine or bromine is preferable in consideration of economy and reactivity. Given as examples of the allene compound represented by Y are paracymene, xylene and benzene. Specifically, a phosphine or phosphites were added ...
1. A monomer comprising an electron-withdrawing group and an electron-donative group represented by the following formula (1): wherein Y represents a iodine atom, chlorine atom or bromine atom; X represents an electron-withdrawing group; B represents an electron-donative group; and Z represents...
