Eleven neutral ligands were investigated in promoting the calcium-catalyzed cross-dehydrocoupling reaction between phenylsilane and diisopropylamine. Among them, N-heterocyclic carbene (NHC) ligand IiPr2Me2 (1,3-diisopropyl-4,5-dimet

[La{N(SiMe3)2}3THF2] (1) is an effective precatalyst for the heterodehydrocoupling of silanes and amines. Coupling of primary and secondary amines with aryl silanes was achieved with a loading of 0.8 mol % of [L

Reactions between PhSiH3 and alkali-metal diamidoalkylmagnesiates ([M{N(SiMe3)2}2MgBu], M=Li, Na, K) provide either selective alkyl metathesis or the formation of polyhydride aggregates contingent upon the identity of the Group 1 metal. In the case of [M{N(SiMe3)2}2MgBu], this reactivity results in a structurally unprecedented dodecametallic decahydride cluster species.

The homoleptic alkaline earth hexamethyldisilazides, [M{N(SiMe 3)2}2]2 (1: M = Mg; 2: M = Ca; 3: M = Sr), have been demonstrated as active pre-catalysts for the cross-dehydrocoupling of Si-H and N-H bonds under mild (25-60 °C) conditions. The reactions are applicable to the coupling of a wide variety of amine and silane substrates and are proposed to occur via a sequence of discrete Si-H/M-N and N-H/M-H metathesis steps. Whereas reactions of dialkyl group 2 species with 2,6-di-iso-propylaniline and phenylsilane delivered a series of well-defined compounds consistent with this rationale, kinetic analysis of the cross-coupling of diethylamine with diphenylsilane provided evidence for a more complex and subtly variable mechanistic landscape. Although reactions performed with all three pre-catalysts presented a number of common features, in every case the calcium species, 2, was found to provide notably superior catalytic activity, an order of magnitude higher than both 1 and 3 and in excess of many previously described benchmark transition metal- or f-element-mediated processes. Variations in overall reaction order, mode of pre-catalyst activation and the nature of the rate determining process are postulated to arise as a consequence of the marked change in M2+ radius and resultant charge density as group 2 is descended.

Addition of two Ln-H bonds of an YbII hydrido complex supported by bulky amidinate ligand to a Ci-C bond lead to the formation of 1,2-dianionic bibenzyl fragment (see picture). Both YbII and hydrido centers are oxidized under the reaction conditions. The resulting YbII- ·6-arene interaction is surprisingly robust: the arene cannot be replaced from the metal coordination sphere when treated with Lewis bases. Copyright
