The amount of the compound shown by formula I and that of the halonium ion generating agent used are preferably 1-3 equivalent and the reaction temperature is suitably 0-25 deg.C. The reaction may be carried out in a solvent such as hexane, benzene, THF, etc. Haloflurinattion of an ...
where the letter n represents the number of carbon atoms in each molecule of the compound and the letter X represents a particular halogen atom. An example of a real chemical described by this formula is fluoromerhane (also known as methyl fluoride), whose molecules have just one carbon atom...
Compounds 10d and 9d, with a chloro atom at the para- and meta- position of the methene group, showed high activities with IC50 values of 6.97 μM and 12.9 μM, respectively. Compound 8d with a chloro atom at the ortho-position of the methene group exhibited identical activity with an...
___ is an aromatic compound in which one or more hydrogen atoms are replaced by halogens. The density of ___ is dependent on several factors: the size of alkane and the number and weight of halogens. A ___ often occurs to haloalkanes and haloarenes because of their slight dipole...
