H2o pyridine reaction
WebMethanesulfonyl chloride (mesyl chloride) is an organosulfur compound with the formula CH 3 SO 2 Cl.Using the organic pseudoelement symbol Ms for the methanesulfonyl (or mesyl) group CH 3 SO 2 –, it is frequently abbreviated MsCl in reaction schemes or equations. It is a colourless liquid that dissolves in polar organic solvents but is reactive … WebWarning: Haloform reaction. Base-driven alpha halogenation yields an unusual result for methyl ketones. Once all enolizable hydrogens are replaced with halogens, this yields a tri-halo-methyl group that is a decent leaving group due to the electron withdrawing effects of the halogens. ...
