-
Page/Page column 9, (2008/06/13)
The invention relates to a method for producing a propargyl alcohol of formula (I) wherein R1 represents a C1-30 alkyl radical, a C3-8 cycloalkyl radical, a C2-20 alkoxyalkyl radical, a C6-14 aryl radical, a C7-20 alkoxyaryl radical, a C7-20 aralkyl radical, a C7-20 alkylaryl radical or H. According to said method, a corresponding aldehyde of formula R1-CHO is reacted with acetylene in the presence of ammonia and a catalytic quantity of between 0.6 and 10 mol % of an alkaline metal hydroxide, an alkaline earth metal hydroxide or an alkaline metal alcoholate, in relation to the aldehyde used. The invention also relates to a method for producing an allyl alcohol of formulae (II) and (III), from the propargyl alcohol (I) produced according to the invention.

Reactions of zirconocene-alkene complexes with aldehydes gave alcohols as coupling products after hydrolysis.The carbon-carbon bond formation proceeded at C1 carbon of alkenes, in sharp contrast to the reactions of alkene-alkene coupling on zirconium.A similar alcohol was also obtained by the reaction of zirconacyclopentane with aldehyde after hydrolysis.Treatment of (C5Me5)2ZrEt2 with styrene gave 2-phenylbutane after hydrolysis contrary to the case of Cp2ZrEt2 which afforded 1-phenylbutane.
