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).

The page provides a comprehensive list of isomers of dodecane, including their chemical structures and properties.
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).
Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2, and thus ethyl acetate is likely to be a good solvent. Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2 , and ethanol is likely to be the best solvent of those tabulated.
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 ...
The line opened at 4.5 points and moved 1.5 points in Ohio State’s favor, while the total has dropped by a point. Nearly 70% of the money is on the over, however, as the total currently sits at ...
CaC 2 + 3I 2 → C 2 I 4 + CaI 2. Diiodoacetylene is a byproduct of the reaction which can later be iodinated to TIE. [1] The action of aqueous solution of potassium hydroxide and iodine on barium carbide in chloroform or benzene can also give TIE. [10] Another synthesis involves mixing separate solutions of diiodoacetylene and iodine in carbon ...
