Metal-organic framework (MOFs) compositions based on nitrogen donor-based organic bridging ligands, including ligands based on 1,3-diketimine (NacNac), bipyridines and salicylaldimine, were synthesized and then post-synthetically metalated with metal precursors, such as complexes of first row transition metals. Metal complexes of the organic bridging ligands could also be directly incorporated into the MOFs. The MOFs provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of asymmetric organic transformations. The solid catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.

An object of the present invention is the use of iron compounds as hydrosilylation and dehydrogenative silylation catalysts.

Claimed is a method involving dehydrogenative silylation of aromatic compounds under Rh-catalysis to give an arylalkoxysilane. The method includes the steps of: 1) combining conditions appropriate to form the arylalkoxysilane, starting materials including A) an alkoxysilane having at least one silicon bonded hydrogen atom per molecule; (I) B) an aromatic compound having a carbon-hydrogen bond; and C) a rhodium bisphospholane catalyst. Additional starting materials such as D) a hydrogen acceptor and/or E) a solvent may be added during step 1). The method may further include 2) recovering the arylalkoxysilane. In a preferred embodiment the Rhodium bisphospholane catalyst is of type (II).

A process produces a C.sub.3- to C.sub.20-alkyltrialkoxysilane by hydrosilylation, wherein alkoxy represents methoxy, ethoxy or propoxy. Initially, a mixture is charged of at least one hydroalkoxysilane from the group of hydrotrialkoxysilane, hydroalkyldialkoxysilane, and hydrodialkylalkoxysilane, and a Pt catalyst. The mixture is then heated to a temperature of 30 C. to 60 C. Subsequently, with mixing, an omega-unsaturated or mono-unsaturated C.sub.3- to C.sub.20-hydrocarbon, at least one carboxylic acid and at least one alcohol as cocatalysts are added to the mixture. The mixture is then reacted and subsequently worked up to obtain the product.
