WebR.A. Biggs, W.W. Ogilvie, in Comprehensive Organic Synthesis (Second Edition), 2014 6.18.4.1.3 Doubly substituted alkenes from vicinal dihalides. The dehalogenation of vic-dihalides is a common method for the synthesis of alkenes.The reaction may be considered by some to be a deprotection because the vicinal halides are normally prepared from … WebThe two-step mechanism below has been proposed for a reaction between nitrogen monoxide and molecular chlorine: Step 1: NO ( g) + Cl 2 ( g) ⇌ NOCl 2 ( g) fast Step 2: NOCl 2 ( g) + NO ( g) 2NOCl ( g) slow. Use this mechanism to derive the equation and predicted rate law for the overall reaction.
