Metal‐free hydrogenation of unfunctionalized olefins is described by Z. H. Li, H. Wang and co‐workers in their Communication on page 7496 ff. Highly Lewis‐acidic hydroborane HB(C 6 F 5 ) 2 was employed as the catalyst. The key step in the catalytic reaction is proposed to involve a borane‐mediated σ‐bond metathesis through a four‐membered ring transition state which resembles the traditional Chinese residential house, Siheyuan, shown in the middle of the picture.
