In this paper we describe the reduction by NaBH4 of some cyclopentanones containing an oxygenated function at the side chain position beta to the carbonyl group, both in the presence and in the absence of CeCl3. Some suggestions for the rationalizati

In this paper we describe how to make a very simple stereoscope for observation of molecular models produced by several recent computer programmes. With this instrument, constructed essentially with four mirrors, the chemist can visualize molecular m
