{ALF} For further examples of the hydroxymagnesation of alkynes, see: Org. Synth. Coll., 8, 507 (1993). Similarly π-allyl complexes with 1,3-dienes can be generated, which react regio-and stereo-selectively with aldehydes to give homoallylic alcohols: J. Chem. Soc., Chem. Commun., 621 (1984):

{ALF} For use, in combination with Mg metal, in formation of titanocycle intermediates, see: J. Org. Chem., 63, 9285 (1998); for reaction scheme, see Triphosgene, A14932.
