Homogeneous catalysis is a vital approach for the synthesis of high-valued chemical substances. L. Brandsma has rigorously chosen and checked the experimental techniques illustrating the catalytic use of copper, nickel, and palladium compounds in natural synthesis. All systems are on a preparative scale, make monetary use of solvents and catalysts, steer clear of poisonous components and feature excessive yields.

0 molar. Apparatus: 1-1 round-bottomed, three-necked flask, equipped with a dropping funnel, a mechanical stirrer and a combination of thermometer and outlet for the addition of bromine and the dehydrobromination; for the preparation of NaOCH 3 the same apparatus with a reflux condenser instead of the outlet-thermometer combination was used. 3 Olefinic, Cycloolefinic and Allenic Halides 37 densed. 0 mol, 160 g) was added dropwise over 45 min with cooling between -30 and -50 DC. After the addition, the diethyl ether was thoroughly removed at water-aspirator pressure.

0 mol, was added in portions of 25-30 ml from the dropping funnel, while cooling the flask in a bath with dry ice and acetone. After addition of each portion the solution became temporarily light -brown. Initially, the temperature of the efficiently stirred mixture was kept between ~10 and ~20 DC, but as the heating effect caused by further additions became less strong, the temperature of the mixture was gradually raised to between +10 and 20 DC (see Note 2). After completion of the addition stirring was continued for an additional period of ~3 h, during which the temperature was allowed to rise above 30 DC.
