The cover picture shows a palladium‐based molecular catalyst for the direct telomerization of glycerol with 1,3‐butadiene, which presents a promising technology allowing direct access to C 8 ‐chain mono‐, di‐, and triethers of glycerol as useful chemical building blocks. Crude glycerol is obtained as a by‐product of biodiesel manufacturing, for example, from rapeseed or sunflowers. In their Communication on page 193 ff., B. M. Weckhuysen et al. report how palladium complexes with methoxy‐substituted triphenylphosphine ligands entail superior catalytic activity in the telomerization of not only pure glycerol but also crude glycerol. The resulting C 8 ‐chain ethers can potentially be applied in the production of surfactant or detergent molecules, as illustrated by the structures set against the foam‐like background.
