Si-N Heterodehydrocoupling with a Lanthanide Compound
[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

Alkaline-Earth-Catalysed Cross-Dehydrocoupling of Amines and Hydrosilanes: Reactivity Trends, Scope and Mechanism
Alkaline-earth (Ae=Ca, Sr, Ba) complexes are shown to catalyse the chemoselective cross-dehydrocoupling (CDC) of amines and hydrosilanes. Key trends were delineated in the benchmark couplings of Ph3SiH with pyrrolidine or tBuNH2. Ae{
Catalytic dehydrogenative Si-N coupling of pyrroles, indoles, carbazoles as well as anilines with hydrosilanes without added base
A base-free, catalytic protocol for the dehydrogenative Si-N coupling of weakly nucleophilic N-H groups of heteroarenes or aryl-substituted amines with equimolar amounts of hydrosilanes is reported. Cooperative Si-H bond activation at a Ru-S bond generates a silicon electrophile that forms a Si-N bond prior to the N-H deprotonation by an intermediate Ru-H complex, only releasing H 2.

New diazasilaphosphetidines and their precursors
A series of aminosilanes (R′HN)2SiR2 have been prepared. In case of bulky substituents R1 the aminolysis of Ph2SiCl2 stops at the (R′HN)ClSiPh2 stage. Replacement of the Cl atom is achieved with LiNHR′ which allows the synthesis of mixed bisaminosilanes (R′HN)(R″HN)SiPh2. The X-ray structures of three of these compounds have been determined. There are no intermolecular N-H...N hydrogen bonds in these compounds in the solid state. Several 1,3,2,4-diazaphosphetidines have been synthesized using bis(N-lithioamino)silanes and bis(N-lithioamino)phosphanes . Amongst these the heterocycle 18 possesses an almost planar four membered N2SiP ring system.

Synthesis and application of some dianilinosilanes, bis (trimethylsilyl) phenylenediamines and dialkyl benzo-1,3,2-diazasilolines as antioxidants
A number of dialkyl or diphenyl dianilinosilanes, bis (trimethylsilyl) phenylenediamines and dialkyl benzo-1,3,2-diazasilolines were synthesized and used as antioxidants for lubricating base oils. Thermal analysis methods (DSC, TG and DTG) and IR techniqu
