BH3-THF络合物 体系反应 1,3-Di(hydroxymethyl)-2-nitrobenzene: 1,3-Dicarboxylic acid-2-nitrobenzene (2.50 g, 11.8 mmol) was dissolved in THF (12.5 mL) and cooled with an ice bath. 1M Borane-THF (59.0 mL, 59.0 mmol) was then added dropwise and the reaction was stirred for 48 hours. ...
3-Methylisoxazolo[4,5-c]pyridine on reduction with BH3:THF gave, via the isolable complex , the tetrahydroisoxazolopyridine . The presence of two chlorine atoms at the 4 and 6 positions directed borane attact to the isoxazole ring, yielding the aminoethylpyridine . Both types of reduction ...
Starting with H 2 Ru 4 (CO) 13 only a small amount of the butterfly cluster (III) (space group Cm, Z=2) is obtained besides (I); however, (I) leads to 60% of (III) in addition to a Ru carbide cluster and unidentified products....
The reaction of Me 2 P-NMe2 with BH 3 ·THF is investigated as a function of temp. and time for mol ratios of 1:0.5 to 1:3.0.doi:10.1002/chin.198723211KANJOLIA, R. K.WATKINS, C. L.KRANNICH, L. K.WILEY‐VCH Verlag GmbHCheminform...

The synthesis of 1,3,2-thiazaborolidine and 2,3-dihydro-2,1,3-borathiazolidines from reaction of ephedrine disulfide and 3,4-dimethyl-5-phenyl-1,3-thiazolidine-2-thione with BH 3 -THF is reported. The two reactions afforded optically active borohydride heterocycles. The X-ray diffraction ...
The reaction is highly stereoselective and proceeds with predominant retention of configuration at the phosphorus atom. A plausible mechanism of reduction of the P=O bond by BH3-THF/Ti(Oi-Pr)(4) has been proposed. (C) 2021 Elsevier Ltd. All rights reserved.Sowa, SylwiaPietrusiewicz, K. ...
Benefits of the apparently lower reaction barrier appear in the reaction of [Cp*FeH2](2) with BH3.THF. The formation and isolation of the novel hydrogen-rich ferraborane arachno-1-Cp*FeB4H11 from the iron hydride contrasts with the production of pentamethylferrocene from a pentamethyl...

The reaction of PdCl 2 (PhCN) 2 and the cyclic adduct formed between 9-BBN and PPh 2 CH 2 CH CH 2 [cyclo-(9-borabicyclo[3.3.1]nonanyl)-propyl(diphenyl)phosphine] has been studied. Opening of the P–B dative bond occurs with the formation of a [PdCl 2 L′] 2 complex in ...
