Abstract

The cover picture shows the P=C=P backbones of stable, neutral diphosphaallenes along with the publication year of the first example reported for given coordination numbers of the phosphorus atoms. Since the synthesis of hexaphenylcarbodiphosphorane (Ph~3~P=C=PPh~3~), a σ^4^,σ^4^‐diphosphaallene, in 1961, only two other classes of compounds with P=C=P sequences have been reported in the past decades. Details of the preparation of the phosphavinylidene(oxo)phosphorane Mes*P(O)=C=PMes* (Mes* = 2,4,6‐tri‐tert‐butylphenyl), a diphosphaallene featuring λ^5^σ^3^‐ and λ^3^σ^2^‐phosphorus atoms, NMR spectroscopic data and the first aspects of its reactivity are described in the article by H. Ranaivonjatovo, J. Escudié et al. on p. 4237 ff.
