Despite wide synthetic application as versatile oxidant and mild Lewis acid, BN has not been used extensively as a nitrating agent. Suspensions of BN in imidazolium ILs were shown to be effective for ring nitration of activated aromatics under mild conditions without the need for external promoters Scheme 3.16.30. 62 For activated substrates, reactions were completed faster and in better. A similar mechanism was proposed by Douglas and Roberts  for the same type of catalyst and reaction conditions. In this proposal, a phenonium ion intermediate is postulated. The latter mechanism was suggested to be preferred for NPB formation in course of cumene conversion at 635-775 K over different types of zeolite catalysts [52,53].

Important questions for Class 11th Chemistry provides you with a great strategy for preparing for the subject of Chemistry. Important questions are very crucial for the final examination as well as for those students who are preparing for the competitive examinations. The solubility of metal ions such as Fe 3 , which form highly insoluble hydroxides, depends on the pH and the presence of complexing agents.In an oxygen-containing atmosphere, iron exists as FeIII because of the positive reduction potential of Fe 3Fe 3 e − → Fe 2 ; E° = 0.77 V.Because ferric hydroxide [FeOH 3] is highly insoluble K sp ≈ 1 × 10 −39, the equilibrium. The formation of Si–C bonds may be by radical–radical coupling or by reaction of a carbanion equivalent with a silicon dangling bond in a reaction related to the S RN 1 process reactions 10–13. 66 While his mechanism should be considered to be speculative at this time, it is analogous to the electrochemical reactions studied by.
