Organic derivatives of boron. reactions of alkanolamines with 2-eehoxy-4,4,6-trimethyl-1,3,2-dioxaborinaes and 2-ethoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane

Abstract

Reactions of alkanolamines [R₁R₂NXOH: R₁ = H, CH₃, C₂H₅, C₄H₉^t, C₆H₅; R₂ = H, CH₃, C₂H₅ and X = -CH₂CH₂-, -CH₂CH₂CH₂-, -CH₂CHCH₃, -C₆H₄CH₂CH₂-, -CH₂CH₂SCH₂CH₂-] with 2-etnoxy-4,4,6-trimethyl-1,3,2-dioxaborinane and 2-ethoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane have been carried out in equimolar ratios. The products so obtained are either distillable liquids (or solids which can be sublimed), soluble in common organic solvents and susceptible to hydrolysis even by atmospheric moisture. The new derivatives are characterized by elemental analyses, I.R., ¹H NMR spectra, refractive indices and molecular weight measurements.
