A general synthesis of substituted fluorenones and azafluorenones was written by Kyba, Evan P.;Liu, Shiuh Tzung;Chockalingam, Kannappan;Reddy, B. Raghava. And the article was included in Journal of Organic Chemistry in 1988.Product Details of 102074-19-1 This article mentions the following:
Twenty-one variously substituted fluorenones and azafluorenones I (X, X1, X2 = CH, N; R, R1 = H, alkyl, halo, etc.) were prepared The key ring-forming step was photochem. Pschorr cyclization of 2-diazoniodiaryl ketones II (same R, R1, X-X2) under direct, (bpy)3Ru(II)- (bpy = 2,2′-bipyridine), or (bpy)3Ru(II)-Cu(II)-photosensitized conditions. Where selectivities were possible in the ring closure, the isomer ratios obtained were in accord with an intermediate aryl radical. In the experiment, the researchers used many compounds, for example, (5-Methylpyridin-3-yl)methanol (cas: 102074-19-1Product Details of 102074-19-1).
(5-Methylpyridin-3-yl)methanol (cas: 102074-19-1) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Product Details of 102074-19-1
