COTRIMERIZATION REACTIONS OF ACETYLENIC ALCOHOLS IN THE PRESENCE OF BISPHOSPHINE NICKEL COMPLEXES. X-RAY MOLECULAR STRUCTURE OF 1,3,5-TRIS(1-HYDROXY-1-METYLETHYL)BENZENE (1,3,5-TIMEB) AND OF THE ADDUCT OF 1,3,5-TIMEB WITH 2,5-DIMETHYLHEX-3-YN-2,5-DIOL

The catalytic cyclotrimerization reactions of 2-methylbut-3-yn-2-ol (Mb), 3-methylpent-4-yn-3-ol (Mp),1-ethynylcyclohexane-1-ol (Ec) and 2,5-dimethylhex-3-yn-2,5-diol (DMED) have been studied in the presence of and .The cyclic cotrimers of Mb-Mp, Mb-Ec and the adduct of 1,3,5-tris(1-hydroxy-1-methylethyl)benzene (TIMEB) with DMED have been characterized.The molecular structures of the adduct TIMEB-DMED and of TIMEB have been determined by X-ray crystallography; TIMEB-DMED: monoclinic, a=16.999(3), b=8.907(1), c=32.142(4) Angstroem, z=8, space group C2/c.Each TIMEB molecule is linked to adjacent TIMEB and DMED molecules to originate on one side centrosymmetric tetramers and on the other side tetramers having 21 symmetry.TIMEB: monoclinic, a=28.001(4), b=5.989(1), c=17.127(3) Angstroem, z=8, space group P21/c.A network of H...O hydrogen bonds links together the molecules of TIMEB.

By cyclotrimerization of the corresponding acetylene derivatives some 1,3,5-trisubstituted benzene derivatives (2a - c, 8a, d) containing three identical chiral groups have been synthesized.The analogous mono- and 1,4-disubstituted products (6, 7) have be
