Sodium as High-efficient Catalyst in Hydroboration of Unsaturated Compounds

The catalysts used to catalyze the hydroboration of nitriles or carbodiimides usually have some disadvantages such as complex structure, high cost, large pollution of environment and so on. It is an important development direction to use the main group metals instead of the transition metals to reduce the costs and realize green catalysis. In this paper, using NaH or NaOH as a catalyst, an efficient reaction of nitrile or carbodiimide with pinacol borane (HBPin) has been achieved. It was found that 3.5 mol% of NaH participated in the hydroboration reaction in a simple and effective method under slight solvent-free circumstances. In addition, intermolecular chemoselectivity hydroboration of nitrile and substrates with different functional groups was also investigated by employing three different catalysts. This reaction uses the inorganic alkali with simple structure, commercially available and low cost to synthesize organoborane compounds, which provides ideas for industrial development.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 54-47-7, in my other articles.

An electrochemical alternative approach to the cyclization of alkynes bearing proximate malonyl moieties

A versatile alternative approach to the synthesis of butenolides, quinolones and 3-pyrrolin-2-ones has been achieved by galvanostatic electrolysis of MeCN/TEATFB solutions and subsequent addition of the cathodic solution to alkynes bearing proximate malonyl moieties. The electrogenerated cyanomethyl anion permits the formation of the reactive anionic intermediates under mild conditions, avoiding the need to use classical bases. ((C) Wiley-VCH Verlag GmbH & Co.

Acceptorless dehydrogenation of amines to nitriles catalyzed by N-heterocyclic carbene-nitrogen-phosphine chelated bimetallic ruthenium (II) complex

We have developed a clean, atom-economical and environmentally friendly route for acceptorless dehydrogenation of amines to nitriles by combining a new dual N-heterocyclic carbene-nitrogen-phosphine ligand R(CNP)(2) (R = o-xylyl) with a ruthenium precursor [RuCl2(eta(6)-C6H6)](2). In this system, the electronic and steric factors of amines had a negligible influence on the reaction and a broad range of functional groups were well tolerated. All of the investigated amines could be converted to nitriles in good yield of up to 99% with excellent selectivity. The unprecedented catalytic performance of this system is attributed to the synergistic effect of two ruthenium centers chelated by R(CNP)(2) and a plausible reaction mechanism is proposed according to the active species found via in situ NMR and HRMS.

The simple and efficient method was developed for the one-pot synthesis of B-substituted aryl derivatives of ortho-carborane with functional groups sensitive to organolithium and organomagnesium reagents using 9-iodo-ortho-carborane and generated in situ organozinc compounds. The method proposed was used to prepare a series of 9-aryl-ortho-carboranes, including those containing nitrile and ester groups, 9-RC6H4-1,2-C2B10H11 (R = p-Me, p-NMe2, p-OCH2OMe, o-OMe, p-OMe, o-CN, p-CN, o-COOEt, m-COOEt, and p-COOEt). It was demonstrated that the same approach can be used for synthesis of diaryl derivatives of ortho-carborane 9,12-(RC6H4)(2)-1,2-C2B10H10 (R = H, p-Me). The solid-state structures of 9-RC6H4-1,2-C2B10H11 (R = p-NMe2, p-OCH2OMe, o-OMe, o-CN, p-CN, m-COOEt, and p-COOEt) and 9,12-(p-MeC6H4)(2)-1,2-C2B10H10 were determined by single crystal X-ray diffraction.
