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).

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).
Hagemann's ester, ethyl 2-methyl-4-oxo-2-cyclohexenecarboxylate, is an organic compound that was first prepared and described in 1893 by German chemist Carl Hagemann. The compound is used in organic chemistry as a reagent in the synthesis of many natural products including sterols , trisporic acids , and terpenoids .
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 reacts with chlorine to give the complex, iodobenzene dichloride, [4] which is used as a solid source of chlorine. Iodobenzene can also serve as a substrate for the Sonogashira coupling , Heck reaction , and other metal-catalyzed couplings.
