Abstract
Compounds of the general formula <FORM:0839583/IV (b)/1> (wherein R is a hydrogen atom or a lower alkyl group with one to five carbon atoms) are made by reacting compounds of the general formula <FORM:0839583/IV (b)/2> with up to 4.5 mols. of sodium borohydride per mol. of compound, in the presence of about 0.1 to 3 mols. of aluminium chloride per mol. of compound, in a solvent consisting of a hydrocarbon glycol or polyglycol fully etherified by a lower alkanol, to obtain a boron complex which is then heated with a mineral acid.
