Synthesis and spectrometric characterization of a true diol bonded phase

摘要: Abstract The syntheses of two types diol bonded phases using a silanization/hydrosilation pathway are described. One product is similar to the phase produced by organosilanization but without problem potential side products and utilizes allyl glycidyl ether as bonding olefin intermediate hydride. second “true” any heteroatoms from surface moiety involves reacting 7-octene-1, 2-diol with hydride silica. Both can be obtained in good yield characterized spectrometrically diffuse reflectance IR Fourier transform cross-polarization magic angle spinning NMR spectrometry. only complication this reaction scheme silica via one alcohol groups (esterification). It appears that when original contains significant number unassociated silanol groups.
