Structures of the three isomers of tolyl group. In organic chemistry, tolyl groups are functional groups related to toluene. [1] They have the general formula CH 3 C 6 H 4 −R, the change of the relative position of the methyl and the R substituent on the aromatic ring can generate three possible structural isomers 1,2 (ortho), 1,3 (meta), and 1,4 (para).
CH 3 OC 6 H 5 + (CH 3 CO) 2 O → CH 3 OC 6 H 4 C(O)CH 3 + CH 3 CO 2 H. Unlike most acetophenones, but reflecting the influence of the methoxy group, methoxyacetophenone undergoes a second acetylation. Many related reactions have been demonstrated. For example, phosphorus pentasulfide (P 4 S 10) converts anisole to Lawesson's reagent, [(CH 3 OC ...

Acetanisole is an aromatic chemical compound with an aroma described as sweet, fruity, nutty, and similar to vanilla. In addition acetanisole can sometimes smell like butter or caramel. [3]
By replacing the acidic hydrogen on phenol with that of an alkyl group, the toxicity of phenols is also reduced; the LD50 of phenol in rats when administered orally is 317 mg/kg, compared to 3500-4000 mg/kg for anisole, the methyl ether. [9] [10] Furthermore, ethers are significantly more hydrophobic than phenols and can be more easily absorbed ...

2,4-Dinitroanisole crystallises in the monoclinic form. The unit cell has these sizes and angles: a=8.772 Å b=12.645 Å c=15.429 Å 81.89°, cell volume is V=1694 Å 3, There are eight molecules in each unit cell, with four positions symmetric.
In organic chemistry, a toluenesulfonyl group (tosyl group, abbreviated Ts or Tos [nb 1]) is a univalent functional group with the chemical formula −SO 2 −C 6 H 4 −CH 3. It consists of a tolyl group, −C 6 H 4 −CH 3, joined to a sulfonyl group, −SO 2 −, with the open valence on sulfur. This group is usually derived from the ...
