Experiment 1: Reduction of Benzophenone with Sodium Borohydride 09/03/10 Aim: The aim of this experiment is to Introduction: The reduction of an organic molecule can involve the addition of two hydrogen atoms across a double or triple bond, or the replacement of a functional group such as an alcohol or halide by hydrogen. There are three basic processes involved in this: The addition, or transfer, of a hydride ion, followed by protonation The addition of molecular hydrogen to multiple bonds The addition of a single electron followed by a proton, then a second electron and another proton In contrast , sodium borohydride is a milder reducing agent which is extremely selectivity. It reduces acid chlorides , aldehydes and ketones quickly, it reduces esters and other functional groups more slowly. Procedure: Benzophenone (1g) was dissolved in ethanol (5ml) where the solution was stirred with a magnetic stirrer until dissolved. Sodium borohydride (0.25g) was dissolved in cold water
