Hydroboration of Phosphaalkynes by HB(C6 F5 )2.

چکیده
The hydroboration of phosphaalkynes with Piers' borane (HB(C6 F5 )2 ) generated unusual phosphaalkenylboranes [RCH=PB(C6 F5 )2 ]2 that persisted as dimers in both solution and the solid state. These P2 B2 heterocycles underwent ring opening when subjected to nucleophiles, such as pyridine and tert-butylisocyanide, to yield monomeric phosphaalkenylborane adducts RCH=PB(C6 F5 )2 (L). DFT calculations were performed to probe the nature of the interaction of phosphaalkynes with boranes.

Boron Lewis Acid-Catalyzed Hydroboration of Alkenes with Pinacolborane: BArF3 Does What B(C6 F5 )3 Cannot Do!
The transition-metal-free hydroboration of various alkenes with pinacolborane (HBpin) initiated by tris[3,5-bis(trifluoromethyl)phenyl]borane (BArF3 ) is reported. The choice of the boron Lewis acid is crucial as the more prominent boron Lewis acid tris(pentafluorophenyl)borane (B(C6 F5 )3 ) is reluctant to react. Unlike B(C6 F5 )3 , BArF3 is found to engage in substituent redistribution with H...
متن کاملA Combined “Electrochemical–Frustrated Lewis Pair” Approach to Hydrogen Activation: Surface Catalytic Effects at Platinum Electrodes
Herein, we extend our "combined electrochemical-frustrated Lewis pair" approach to include Pt electrode surfaces for the first time. We found that the voltammetric response of an electrochemical-frustrated Lewis pair (FLP) system involving the B(C6 F5 )3 /[HB(C6 F5 )3 ]- redox couple exhibits a strong surface electrocatalytic effect at Pt electrodes. Using a combination of kinetic competition s...
متن کاملCerium-Catalyzed Hydrosilylation of Acrylates to Give α-Silyl Esters.
The homoleptic organocerium complex Ce{C(SiHMe2 )3 }3 (1) reacts with B(C6 F5 )3 to produce the zwitterionic bis(alkyl) hydridoborato Ce{C(SiHMe2 )3 }2 HB(C6 F5 )3 (2). NMR and IR spectroscopy and X-ray crystallography indicate that each alkyl ligand contains two bridging Ce↼H-Si interactions in both 1 and 2. Compound 2 serves as a precatalyst for the hydrosilylation of acrylates to give α-sily...
متن کاملFormation of a dihydroborole by catalytic isomerization of a divinylborane.
Diphenylamino(divinyl)borane (1a) adds two molar equivalents of Piers' borane [HB(C6F5)2] to give the expected double hydroboration product. In contrast diisopropylamino(divinyl)borane (1b) reacts cleanly already with one molar equivalent of HB(C6F5)2 to give the α-borylated tetrahydroborole derivative 10 in good yield. Subsequent treatment of 10 with benzaldehyde proceeded by retro-hydroborati...
متن کاملExpanding Water/Base Tolerant Frustrated Lewis Pair Chemistry to Alkylamines Enables Broad Scope Reductive Aminations
Lower Lewis acidity boranes demonstrate greater tolerance to combinations of water/strong Brønsted bases than B(C6 F5 )3 , this enables Si-H bond activation by a frustrated Lewis pair (FLP) mechanism to proceed in the presence of H2 O/alkylamines. Specifically, BPh3 has improved water tolerance in the presence of alkylamines as the Brønsted acidic adduct H2 O-BPh3 does not undergo irreversible ...
