Benzyl chloride, or α-chlorotoluene, is an organic compound with the formula C 6 H 5 CH 2 Cl. This colorless liquid is a reactive organochlorine compound that is a ...
Benzyl group and derivatives: Benzyl group, benzyl radical, benzyl amine, benzyl bromide, benzyl chloroformate, and benzyl methyl ether. R = heteroatom, alkyl, aryl, allyl etc. or other substituents. In organic chemistry, benzyl is the substituent or molecular fragment possessing the structure R−CH 2 −C 6 H 5.
Chlorobenzene (abbreviated PhCl) is an aryl chloride and the simplest of the chlorobenzenes, consisting of a benzene ring substituted with one chlorine atom. Its chemical formula is C 6 H 5 Cl. This colorless, flammable liquid is a common solvent and a widely used intermediate in the manufacture of other chemicals.
For example, the chloro derivative C 6 H 5 Cl is normally called chlorobenzene, although it could be called phenyl chloride. In special (and rare) cases, isolated phenyl groups are detected: the phenyl anion ( C 6 H − 5 ), the phenyl cation ( C 6 H + 5 ), and the phenyl radical ( C
In terms of Lewis structures, formal charge is used in the description, comparison, and assessment of likely topological and resonance structures [7] by determining the apparent electronic charge of each atom within, based upon its electron dot structure, assuming exclusive covalency or non-polar bonding.
Benzoyl chloride, also known as benzenecarbonyl chloride, is an organochlorine compound with the formula C 7 H 5 ClO. It is a colourless, fuming liquid with an irritating odour, and consists of a benzene ring ( C 6 H 6 ) with an acyl chloride ( −C(=O)Cl ) substituent .
2- and 4-chlorotoluene are precursors to the corresponding benzyl chloride (ClC 6 H 4 CH 2 Cl), benzaldehyde (ClC 6 H 4 CHO), and benzoyl chloride (ClC 6 H 4 C(O)Cl). [2] 2- and 4-chlorotoluenes are converted to 2-chlorobenzonitrile and 4-chlorobenzonitrile, respectively. [3] Chlorotoluenes are precursors to dichlorotoluenes.
For example, benzyl chloroformate is used to introduce the Cbz (carboxybenzyl) protecting group and fluorenylmethyloxycarbonyl chloride is used to introduce the FMOC protecting group. Chloroformates are popular in the field of chromatography as derivatization agents. They convert polar compounds into less polar more volatile derivatives.
