Nano‐ferrite‐supported Cu nanoparticles (Fe‐dopamine‐Cu NPs) catalyzed anti‐Markovnikov‐selective hydroboration of alkenes with B2pin2 is reported under mild reaction conditions. This protocol can be applied to a broad range of substrates with high functional group compatibility. In addition, we demonstrated the use of Fe‐dopamine‐Cu NPs as a catalyst for the β‐borylation of α,β‐unsaturated ketones and ester, providing alkylboronate esters in up to 98% yield. Reuse of the magnetically recyclable catalyst resulted in no significant loss of activity in up to five reaction runs for both systems.

Over the past decade, the reactivity of 2-phosphaethynolates (OCP¯), a heavier analogue of the cyanate anion, is the subject of momentous interest in modern organometallic chemistry. Its use as a...

The mild borylation of alkyl bromides and chlorides with bis­(neopentylglycolato)­diborane (B2neop2) mediated by iron-bis amide is described. The reaction proceeds with a broad substrate scope and good functional group compatibility. Moreover, sufficient catalytic activity was obtained for primary and secondary alkyl halides. Mechanistic studies indicate that the reaction proceeds through a radical pathway.

The CeO2-nanoparticle catalysed hydroboration of carbonyl compounds with HBpin (pin = OCMe2CMe2O) is reported to afford corresponding borate esters in excellent yield. A series of aromatic and aliphatic aldehydes and...

The protoboration of alkenes and alkynes with B 2 pin 2 (pin = OCMe 2 CMe 2 O) using a heterogeneous CeO 2 nanorods catalyst has been developed to afford the corresponding alkyl and vinyl boronate esters in 41-99% yield under mild reaction conditions. A series of aromatic and aliphatic alkenes and alkynes with synthetically important functional groups were well tolerated. In both the systems, the catalyst could be reused for up to six runs without significant loss in activity. Stoichiometric reactions revealed that the protoboration may proceed through the in situ formed catalytically active boryl species.

An efficient synthesis of alkylboronate esters by copper nanoparticle stabilised on nitrogen-doped carbon nanotubes (N-CNT) catalysed alkyl halides borylation is reported. This nanocatalyst provides a practical access to alkylboronate esters...

The inside cover picture illustrates the magnetically separable Cu nanocatalyst for the β‐borylation of α,β‐unsaturated carbonyl compounds and anti‐Markovnikov‐selective hydroboration of alkenes, providing alkylboronate esters in high yields. The use of easy recyclable non‐noble metal nanoparticle based catalysts with high efficiency are in great demand from a standpoint of environmental and sustainable chemistry.

An efficient and anti-Markovnikov selective transition metal- and solvent-free Lewis base-mediated protoboration of aromatic and aliphatic alkenes with bis(pinacolato)diboron (B2pin2) as the boron reagent is reported. This protocol is practical...
