Bridge over troubled iron: An N‐bridged diiron tetra‐tert‐butylphthalocyanine complex, usually employed for oxidation reactions, also catalyzes the addition of acetaldehyde to olefins (see scheme) to provide methylketones with a high selectivity (up to 92 %) and high turnover numbers (3600–5700).

A facile method for the synthesis of challenging medium-sized cyclic ethers has been developed via a novel oxidative rearrangement of benzylic tertiaryalcohols. The reaction provides access to cyclic acetals with diverse substitution at both C2 and the aromatic ring. The unique reactivity is enabled by poly(cationic) hypervalent iodine reagents and represents the first synthetic application of this
