2-Methyl anthraquinone synthesis
- Product Name:2-Methyl anthraquinone
- CAS Number:84-54-8
- Molecular formula:C15H10O2
- Molecular Weight:222.24
2-Methyl anthraquinone is produced by the reaction of phthalic anhydride and toluene.It can be chlorinated to give 1-chloro-2-methylanthraquinone. Nitration gives 1-nitro-2-methylanthraquinone, which can be reduced to 1-amino-2-methyl derivative.

Reaction of Alkynes with Ethylenediamine - General Procedure
General procedure: A mixture of alkyne 1a-b, 5a-g, 7a-b (1.6 mmol) and ethylenediamine (5 ml, 75.0 mmol) in pyridine was refluxed for 1-50 h. Solvent was removed under reduced pressure and the crude reaction mixture was purified by column chromatography (toluene/ethyl acetate) to give pure products (Table 2). In the case of 2-(phenylethynyl)pyridine (7b), the reaction mixture was treated with an ethanolic solution of 2,4-dinitrophenylhydrazine to afford (Z)-2-(2-(2-(2,4-dinitrophenyl)hydrazono)-2-phenylethyl)pyridine; yield 35%, mp 196-198°C (lit. 192-194°C[34]).
