Addition of bis(diisopropylamino)cyclopropenylidene (BAC) to [U(NR2)3(CCPh)] (R = SiMe3) results in dimerization and protonation of two BAC molecules, followed by ring-opening and C–H activation to generate a azetidin-2-ylidenemethyl ring.

K2RbSc(PO4)2 can be characterized as a derivative of glaserite-type K3Na(SO4)2 obtained in a chemical co-substitution manner. Its isostructural lanthanide analogues K2RbEr(PO4)2 and K2RbLu(PO4)2 were also successfully prepared indicating high structural tolerance of the skeleton of K2RbSc(PO4)2.

A Co(II) complex, [CoII(L)2(H2O)2](ClO4)2, [L = bis(3,5-dimethylpyrazolyl)methane] in acetonitrile at −40 °C, in presence of H2O2 and NEt3 afforded [CoIII(L)2(O22−)]+, 1a. Addition of NO gas to this resulted in [CoII(L)2(NO3)]ClO4, (2) via a putative Co(II)-peroxynitrite intermediate.
