“…Literature understanding of 1 and the observed reaction chemistry provide the basis for a working mechanistic hypothesis for this catalysis (Scheme ). Activation of 1 would arise from migratory insertion of the methyl ligand, rather than protonation, based on the relatively low acidity of these phosphine substrates and prior study of protonolysis and migratory insertion reactions at 1 . This proposal is buttressed by the persistence of 1 at the end of catalysis.…”

The ubiquitous half-sandwich iron complex [CpFe(CO) Me] (Cp=η -C H ) appears to be a catalyst for α-phosphinidene elimination from primary phosphines. Dehydrocoupling reactions provided initial insight into this unusual reaction mechanism, and trapping reactions with organic substrates gave products consistent with an α elimination mechanism, including a rare example of a three-component reaction. The substrate scope of this reaction is consistent with generation of a triplet phosphinidene. In all, this study presents catalytic phosphinidene transfer to unsaturated organic substrates.

“…Deprotonation of HPPh 2 by the N‐Ar arm is followed by phosphide/alkene addition after which the intermediate is protonated again. This mechanism is corroborated by the fact that aniline ( pK a 30.7) is less acidic than HPPh 2 ( pK a 21.7) …”

Tetranuclear Strontium and Barium Siloxide/Amide Clusters in Metal‐Ligand Cooperative Catalysis

One-pot reaction of 2,6-iPr 2 -aniline (DIPP-NH 2 ) with (Me 2 SiO) 3 and Sr[N(SiMe 3 ) 2 ] 2 (SrN′′ 2 ) gave a tetranuclear cluster consisting of four dianions [OSiMe 2 N-DIPP] 2and four Sr 2+ ions solvated each by one THF ligand. The general applicability of this method was investigated by variation of amine and metal. Anilines with smaller substituents led to insoluble uncharacterized coordination polymers, whereas bulkier anilines gave soluble product mixtures that could not be purified. Primary alkylamines neither led to isolable products. Introduction of a tBu group in para-position of DIPP-NH 2 , however, gave an isostruc- [a]
