CH 220 1st Edition Lecture 10 Outline of Current Lecture I. Hydrogenation II. Hydroxylation III. Cleavage Current Lecture I. Hydrogenation Addition of H-H across a C=C Requires Pt, Pd, Ni or PtO2 H is absorbed on the catalyst This process doesn’t happen in a solution, it happens on the surface of the catalyst (solid state) This means that it cannot create free ions, so can’t see + and – moving around Always gives a cis configuration (called a syn-mechanism) This is performed in a metal container that can be pressurized The bottom is covered with platinum particles (which can be reused, as it doesn’t get consumed in the reaction) Pressure is increased enough so that the ethylene (or other molecule) sits on top of the catalyst and carbons get bonded to the catalyst Hydrogen is pumped in, which has an affinity for the catalyst Ethylene (or other molecule) doesn’t have such a great affinity for the catalyst and so floats away II. Hydroxylation Adding 2 x OH groups Has a syn-mechanism, resulting in a cis product These notes represent a detailed interpretation of the professor’s lecture.
