, p. 3976 - 3982 (2007/10/03)
Substituted styrenes with linear alkyl substituents (C6 to C12) at the para position on the ring were synthesized and polymerized using the (Me)5CpTi(OMe)3/MAO catalytic system. Increased polymerization activiti
DETHIOACETALISATION DE DITHIANNES-1,3 PAR DES TRIBROMURES DE PHOSPHONIUM
Cristau, Henri-Jean,Bazbouz, Akram,Morand, Philippe,Torreilles, Eliane

Methyltriphenylphosphonium tribromide 1 acts as an efficient mild dethioketalization reagent with high selectivity for 2-phenyl and 2-vinyl 1,3-dithiannes 2 versus 2-alkyl 1,3-dithiannes and without any secondary bromination reaction of the investigated substrates.The reaction was also succesful with trimethylphenylammonium tribromide.
Multiple Melting Behaviour in Square-planar trans-Bis-(1-p-n-alkylphenylbutane-1,3-dionato)copper(II) - The Effect of Alkyl Chain Length

The title complexes having different n-alkyl groups from methyl to dodecyl have synthesized.All these complexes exhibit solid polymorphism.The number of polymorphs depends on the length of the alkyl chain: two for n (the number of carbon atoms) = 0-2, three for n = 3-5 and 12, and four for n = 6-11, respectively.Each polymorphic form except those with the highest m.p.s. exhibits multiple melting behaviour: double melting for n = 0-5,8, and 12, and triple melting for n = 6-11 except 8.The m.p.s. of the complexes with alkyl groups of odd carbon atoms are higher than those with even atoms, while the respective ligand solids show the opposit e even-odd effect in their m.p.s.
