Reduction of CO2 to Trimethoxyboroxine with BH3 in THF
journal contribution
posted on 2015-12-17, 05:58 authored by Koji Fujiwara, Shogo Yasuda, Tsutomu MizutaCommercially available THF solutions
of BH3·THF,
which contain 0.5 mol % of NaBH4 as a stabilizing reagent
for BH3·THF, react with 1 atm of CO2 at
room temperature to form trimethoxyboroxine, (MeOBO)3,
in 87% yield after 12 h. Since no reaction took place in the absence
of NaBH4, NaBH4 was found to work as a promoter
or catalyst for the reduction of CO2 with BH3 to the methoxy compound. A similar reaction using HCOONa in place
of NaBH4 also gave (MeOBO)3 in comparable yield.
