Catalytic hydroboration by an imido-hydrido complex of Mo(IV).

چکیده
The imido-hydrido complex (ArN)Mo(H)(Cl)(PMe(3))(3) catalyses a variety of hydroboration reactions, including the first example of catalytic addition of HBCat to nitriles to form the bis(borylated) amines RCH(2)N(BCat)(2). The latter species easily undergoes chemoselective coupling with aldehydes R'C(O)H to yield imines RCH(2)N=C(H)R'.

Imido-hydrido complexes of Mo(IV): catalysis and mechanistic aspects of hydroboration reactions.
Imido-hydrido complexes (ArN)Mo(H)(Cl)(PMe3)3 (1) and (ArN)Mo(H)2(PMe3)3 (2) (Ar = 2,6-diisopropylphenyl) catalyse a variety of hydroboration reactions, including the rare examples of addition of HBCat to nitriles to form bis(borylated) amines RCH2N(BCat)2. Stoichiometric reactivity of complexes 1 and 2 with nitriles and HBCat suggest that catalytic reactions proceed via a series of agostic bor...
متن کاملTransition metal free catalytic hydroboration of aldehydes and aldimines by amidinato silane.
The transition metal free catalytic hydroboration of aldehydes and ketones is very limited and has not been reported with a well-defined silicon(iv) compound. Therefore, we chose to evaluate the previously reported silicon(iv) hydride [PhC(NtBu)2SiHCl2], (1) as a single component catalyst and found that it catalyzes the reductive hydroboration of a range of aldehydes with pinacolborane (HBpin) ...
متن کاملSelective oxidation and ammoxidation of propene on bismuth molybdates, ab initio calculations
In this paper we use first principles quantum mechanical methods (B3LYP flavor of density functional theory) to examine the mechanism of selective oxidation and ammoxidation of propene by BiMoOx catalysts. To do this we use finite clusters chosen to mimic likely sites on the heterogeneous surfaces of the catalysts. We conclude that activation of the propene requires a Bi(V) site while all subse...
متن کاملMagnesium-catalysed hydroboration of isonitriles.
A β-diketiminato magnesium alkyl complex is shown to be an effective pre-catalyst for the first reported catalytic hydroboration of organic isonitriles, RNC, with HBpin. The reaction proceeds under mild conditions when R = alkyl and provides access to the corresponding 1,2-diborylated amine products.
