Three‐fold alkene metatheses are used to access the family of molecular gyroscopes shown in the cover picture. As described by J. A. Gladysz and co‐workers in their Communication on page 5537 ff. the gyroscopes consist of a phosphorus–iron–phosphorus axis, an {Fe(CO) 3 } or {Fe(CO) 2 (NO)} + “rotator”, and three (CH 2 ) n “spokes” that connect the phosphorus termini. These are believed to be the first systems that rigorously duplicate the connectivity and symmetry of toy gyroscopes (shown in the background).
