nitrosobenzene मीनिंग इन हिंदी

उदाहरण वाक्य

1. Nitrosobenzene can also be prepared by oxidation of aniline using peroxymonosulfuric acid ( Caro's acid ).
2. Another study concerns the proline catalyzed aminoxylation of propionaldehyde by nitrosobenzene ( " scheme 2 " ).
3. Most characteristically, nitrosobenzene condenses with active methylene groups, such as those of malonic esters and benzyl cyanide.
4. Blackmond in 2004 also found oxazolidinones as intermediates ( NMR ) in a related proline-catalysed ?-aminooxylation of propanal with nitrosobenzene:
5. Chiong Teck Wong of the Institute of High Performance Computing Singapore studied the similar oxyamination reaction of nitrosobenzene with butanal using a chiral prolinol silyl ether catalyst.
6. Wong suggests that the reaction mechanism of the ( S )-Cat catalyzed N-nitroso aldol reaction between nitrosobenzene and butanal proceeds via an enol intermediate and not via an enamine intermediate.
7. Examples of recently studied reactions are : Acid-base, hydration-dehydration and tautomeric equilibria involving 1, 3, 5-and 1, 2, 4-triazines, selenous acid and mytomicin C, reactions of bile acids, cholesterol, and other sterols in strongly acidic media, additions of nucleophiles, such as glutathione, to nitrosobenzene, etc . Most of these studies involve biologically important compounds and their investigations are essential both for development of analytical methods and for their contribution to a better understanding of biological activity.
