The cover picture shows the framework of ( t BuCP) 4 , the first tetraphosphacubane, together with its surprisingly straightforward route of formation. This phosphorus‐carbon compound was simply obtained by heating t BuCP at ca. 130°C. This thermal cyclooligomerization of a phosphaalkyne offers a new perspective on the diverse reactivity of this class of compounds. Furthermore, the chemistry of polycyclic polyphosphorus hydrocarbons now appears to be developing apace with that of polyphosphanes and of the well‐investigated polycyclic hydrocarbons. These developments promise to provide new insights into the structure and bonding of main‐group compounds. Further details on ( t BuCP) 4 are reported by M. Regitz et al. on page 1013 ff.
