Recycling polymers: In the present study, the efficient zinc-catalyzed depolymerization of a variety of artificial polyethers has been investigated. Chloroesters were obtained as the depolymerization products, which are suitable precursors for new polymers. By using straightforward zinc salts, extraordinary catalyst activities and selectivities were feasible (see scheme).

Iron will: The iron-catalyzed depolymerization of a range of polyethers is studied. The products of the depolymerization reactions are chloroesters, which can be used as starting materials for new polymers. In the presence of simple iron salts extraordinary catalyst activities and selectivities are feasible at low temperature.

Nickel‐catalyzed hydrodecyanation of aryl and alkyl cyanides with tert‐butylmagnesium chloride has been examined in detail. With a straightforward nickel complex as the precatalyst, good to excellent yields and chemoselectivity were achieved for a variety of organic cyanides.
