The page provides a comprehensive list of isomers of dodecane, including their chemical structures and properties.
The parent isoindole was prepared by flash vacuum pyrolysis of an N-substituted isoindoline. [5] N-Substituted isoindoles, which are easier to handle, can be prepared by dehydration of isoindoline-N-oxides. They also arise by myriad other methods, e.g., starting from xylylene dibromide (C 6 H 4 (CH 2 Br) 2).

3 CH 3 OH + PI 3 → 3 CH 3 I + H 2 PO 3 H. Alternatively, it is prepared from the reaction of dimethyl sulfate with potassium iodide in the presence of calcium carbonate: [6] (CH 3 O) 2 SO 2 + KI → CH 3 I + CH 3 OSO 2 OK. Iodomethane can also be prepared by the reaction of methanol with aqueous hydrogen iodide: CH 3 OH + HI → CH 3 I + H 2 O
To a stirred solution of p-(3-hydroxypropyl)phenol (152 mg, 1 mmol) and pyridine (0.3 mL) in acetonitrile (10 mL) at 0° was added a solution of IBTA (430 mg, 1 mmol) in acetonitrile (2 mL). The mixture was stirred at room temperature for 10 minutes, diluted with water, and extracted with diethyl ether (3 × 10 mL).
Diiodomethane is a reagent for installing the CH 2 group. In the Simmons–Smith reaction, it is a source of methylene. [4] In fact the Simmons–Smith reaction does not produce free carbene but proceeds via Zn-CH 2 I intermediates. Diiodomethane is also a source of the equivalent of CH 2+ 2. The synthesis of Fe 2 (CH 2)(CO) 8 illustrates this ...
Ethyl iodide (also iodoethane) is a colorless flammable chemical compound. It has the chemical formula C 2 H 5 I and is prepared by heating ethanol with iodine and phosphorus . [ 2 ] On contact with air, especially on the effect of light, it decomposes and turns yellow or reddish from dissolved iodine.
Iodobenzene is commercially available, or it can be prepared in the laboratory from aniline via the diazotization reaction. In the first step, the amine functional group is diazotized with hydrochloric acid and sodium nitrite.
