Provided herein are silane compounds. The silane compounds can be used as organocatalysts and as sensors. Accordingly, also provided are methods of using the silane compounds described herein as catalysts. Methods of using the silane compounds described herein as catalysts can involve contacting a first organic species and a second organic species with a catalytically effective amount of a silane compound or a catalyst composition comprising a silane compound under conditions effective to form the desired product. The product can preferably be enantioenriched.

Enantiopure silanediols derived from BINOL are an innovative family of stereoselective hydrogen-bond donor (HBD) catalysts. Silanediols incorporated into a BINOL framework are attractive catalysts, as they are readily accessible and highly customizable. Structural modifications of the BINOL backbone affect the reactivity and selectivity of the silanediol catalysts in the additions of silyl ketene acetals

Enantioselective heteroatom-directed C(sp3)–H borylation reactions of 2-aminopyridines and 2-alkylpyridines with Rh- and Ir catalytic systems using commercially available chiral monophosphine ligands, respectively, were developed. This methodology provides an innovative example of a homogeneous catalytic system for C(sp3)–H borylation, and allows the direct synthesis of optically active alkylboronates
