REACTION OP CYCLOALKANONES WITH COPPER(II) HALIDE. III. REACTION OP CYCLOHEXANONES AND STEROIDAL KETONES WITH COPPER(II) HALIDE IN ETHYLENE GLYCOL
It was found that, in the presence of small amounts of copper(II) halide, cyclohexanones and steroidal ketones in ethylene glycol gave smoothly their acetals. Moreover, the reaction of steroidal ketones with 5 molar equiv. of copper(II) halide in ethylene glycol/dioxane (1:1) gave their α-haloacetals.
