Structure of the chloromethyl group. In organic chemistry, the chloromethyl group is a functional group that has the chemical formula −CH 2 −Cl. The naming of this group is derived from the methyl group (which has the formula −CH 3), by replacing one hydrogen atom by a chlorine atom. Compounds with this group are a subclass of the ...
Fluorobenzenes are a group of aryl fluorides/halobenzenes consisting of one or more fluorine atoms as substituents on a benzene core. They have the formula C 6 H 6–n F n, where n = 1–6 is the number of fluorine atoms.
PhN=N-N(CH 2) 5 + 2 HF → PhF + N 2 + [(CH 2) 5 NH 2]F. Historical note: in Wallach's era, the element fluorine was symbolized with "Fl". Thus, his procedure is subtitled "Fluorbenzol, C 6 H 5 Fl". [1] On the laboratory scale, PhF is prepared by the thermal decomposition of the benzenediazonium tetrafluoroborate: PhN 2 BF 4 → PhF + BF 3 + N 2
The half-life of this substance in terms of volatilization in the river, lagoon and lake is 2.1 h, 25 h and 18 days, respectively. [ 20 ] [ 21 ] The amount of methyl chloride in the stratosphere is estimated to be 2 × 10 6 tonnes per year, representing 20–25% of the total amount of chlorine that is emitted to the stratosphere annually.
Chloromethyl methyl ether (CMME) is a compound with formula CH 3 OCH 2 Cl. A colorless liquid, it is a chloroalkyl ether.It is used as an alkylating agent.In organic synthesis, it is used for introducing the methoxymethyl ether (MOM) protecting group, [3] and is thus often called MOM-Cl or MOM chloride.
