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. ...
The novel arachno-2-tungstametallaborane, [WH 3(PMe 3) 3B 3H 8[, has been made in high yield (>90%) by the reaction of the monoborane BH 3路THF (THF = tetrahydrofuran) with [WH 6(PMe 3) 3]. This represents a controlled transition metal mediated synthesis of a higher borane ...
