✦ Synopsis

In conventional metathetical reactions, product separation is based on solubility product differences, and the resulting products are often impure and require purification by recrystallization. A new approach to product separation is described that relies on the formation of an unstable, volatile by-product, such as NH 4

ϩ CH 3 O Ϫ . This method provides very pure and anhydrous
