Kinetic and mechanistic examinations of reductive transformation pathways of brominated methanes with nano-scale Fe and Ni/Fe particles.
Water Res. 41(4) , 875-83, (2007) In this study, carbon tetrabromide (CTB), bromoform (BF) and dibromomethane (DBM) were the target compounds investigated for their reduction kinetics and pathways with nano-scale Fe and Ni/Fe particles synthesized in laboratory. The BET surface areas of these... |

Structures of bromoalkanes' photodissociation in solution by means of ultrafast extended x-ray absorption fine-structure spectroscopy.
Proc. Natl. Acad. Sci. U. S. A. 99(20) , 12556-61, (2002) The structures of initial and final products of bromoalkanes' photodisociation reaction in cyclohexane solution have been measured with a bond length accuracy of 0.02 A by means of ultrafast time-resolved extended x-ray absorption fine structure spectroscopy.... |

A strategy for sequence control in vinyl polymers via iterative controlled radical cyclization.
Nat. Commun. 7 , 11064, (2016) There is a growing interest in sequence-controlled polymers toward advanced functional materials. However, control of side-chain order for vinyl polymers has been lacking feasibility in the field of polymer synthesis because of the inherent feature of chain-g... |

Photodissociation dynamics of CBr4 at 267 nm by means of ion velocity imaging.
J. Chem. Phys. 125(13) , 133311, (2006) The photodissociation dynamics of CBr4 at 267 nm has been studied using time of flight (TOF) mass spectrometry and ion velocity imaging techniques. The photochemical products are detected with resonance enhanced multiphoton ionization (REMPI) as well as singl... |

Long term puzzles of the CH and CD energetics and related phenomena revisited; solutions sought through REMPI-photofragmentations of bromomethanes.
Phys. Chem. Chem. Phys. 18 , 1797-806, (2016) Ever since the pioneering work by Herzberg and Johns in 1969 (The Astrophysical Journal, 1969, 158, 399) the spectral assignment and the energetics of the fundamental molecular fragment CH, in the region of 63 000-65 000 cm(-1) (7.81-8.06 eV), have remained a... |

Allyl group as a protecting group for internucleotide phosphate and thiophosphate linkages in oligonucleotide synthesis: facile oxidation and deprotection conditions.
Org. Lett. 2(3) , 243-6, (2000) [reaction: see text] The allyl group, which serves as a protecting group for an internucleotide bond for both phosphates and phosphorothioates, can be easily removed by good nucleophiles under weakly basic or neutral conditions. For a practical synthesis on s... |

An easy access to halide ion-catalytic alpha-glycosylation using carbon tetrabromide and triphenylphosphine as multifunctional reagents.
Org. Biomol. Chem. 1(14) , 2518-21, (2003) The reaction of a 2-O-benzyl-1-hydroxy sugar with CBr4 and Ph3P generates a glycosyl bromide in situ, which is coupled with an acceptor alcohol in the presence of N,N-tetramethylurea to afford an alpha-glycosyl product virtually quantitatively. In a proposed ... |

Exploring solvent effects upon the Menshutkin reaction using a polarizable force field.
J. Phys. Chem. B 114(25) , 8425-30, (2010) The energetics of the Menshutkin reaction between triethylamine and ethyl iodide have been computed using B3LYP and MP2 with the LANL2DZ, LANL2DZd, SVP, MIDI!, 6-311G(d,p), and aug-cc-PVTZ basis sets. Small- and large-core energy-consistent relativistic pseud... |

Effect of carbon tetrabromide on the morphology of GaAs nanowires.
Nanotechnology 22(16) , 165603, (2011) Carbon is a commonly used p-type dopant in planar III-V semiconductors, however its use in nanowire (NW) growth has been much less reported. In this work we show that the morphology of gold assisted GaAs NWs can be strongly modified by the presence of CBr(4) ... |

A mild and selective cleavage of trityl ethers by CBr4-MeOH.
Carbohydr. Res. 329(4) , 885-8, (2000) Trityl ethers are selectively deprotected to the corresponding alcohols in high yields by CBr4 in refluxing methanol under neutral reaction conditions. Other hydroxyl protecting groups like isopropylidene, allyl, benzyl, acetyl, benzoyl, methyl, tosyl, prenyl... |
