TADDOL (=alpha,alpha,alpha?,alpha?-Tetraaryl-1,3- dioxolane-4,5-dimethanol) and the corresponding dichloride are converted to TADDAMINs (=(4S,5S)-2,2,N,N?-tetramethyl-alpha,alpha,alpha?, alpha?-tetraphenyl-1,3-dioxolan-4,5-dimethanamines) (Scheme 2) and ureas, 12-15, and to TADDOP derivatives with seven-membered O-P-O ester rings (Schemes 3 and 4). Cl/P-Replacement via the Michaelis-Arbuzov reaction (Scheme 7) on mono- and dichlorides, derived from TADDOL, are described. It was not possible to obtain phosphines with the P-atom attached to the benzhydrylic C-atom of the TADDOL skeleton (Schemes 6 and 7). The X-ray crystal structures (Figs. 1 and 2) of ten of the more than 30 new TADDOL derivatives are discussed. Full experimental details are presented. Copyright

Title full: Halide-bridged arsine- and phosphine-capped diruthenium complexes, [(R3As)3Ru(mu-X)3Ru(AsR3) 3]+ and [(R3P)3Ru(mu-X)3Ru(PR3) 3]+ (X = Cl or Br), as precursors to confacial mixed-valence ruthenium ‘blues’: Spectroelectrochemical studies spanning the binuclear oxidation states II,II, II,III and III,III. A series of six tertiary-arsine-capped binuclear complexes, [L3Ru(mu-X)3RuL3][CF3SO 3] (L = AsMe3, AsMe2Ph or AsMePh2; X = Cl or Br) together with a full range of purely PR3-capped analogues and the mixed-ligand complex [(Ph3P)(Me3As)2Ru(mu-Cl) 3Ru(AsMe3)2(PPh3)][CF 3SO3] have been characterised. The previously neglected arsine-capped compounds share the well defined electrochemical behaviour of their phosphine congeners. Stepwise reversible oxidations connect the Ru2II,II closed-shell d6d6 (=12-e) resting state with the d5d6 (11-e) and d5d5 (10-e) levels, and all the mixed-valence [L3Ru(mu-X)3RuL3]2+ species can be characterised through electrogeneration in CH2Cl2 at -60C. Unexpectedly, the Ru2II,III arsine complexes strongly resemble the classical ruthenium ‘blues’ where L = NH3 or H2O. For such valence-delocalised systems the visible region ordinarily contains an intense sigma ? sigma* band (the source of the intense blue colour) together with a much weaker, near-infrared deltapi* ? sigma* band. Bonding within the {RuX3Ru}2+ core can then be monitored directly by nusigma?sigma*. The distinctly different spectral appearance of the more familiar PR3-capped mixed-valence compounds has been a long-standing puzzle, but the twenty electrogenerated 11-e binuclear systems assembled here with various AsR3 or PR3 terminal ligands are all delocalised, and clearly belong within a continuum of electronic behaviour with steadily decreasing metal-metal interaction. In all, nusigma?sigma* declines over a considerable range from 17 000 to below 5000 cm-1, with the ligands ranked as follows: L = NH3 (and 1,4,7-trimethyl-1,4,7-triazacyclononane) > H2O > Cl, Br (i.e. nonahalides) > AsR3 > PR3 and mu-Cl > mu-Br. These changes are well correlated with systematic trends in the g., and g? components of the axial g tensor, and also with the gap between the stepwise oxidation potentials which shrinks from 1.2 to 0.45 V. For the PR3 complexes the decrease in nusigma?sigma* is accompanied by progressive intensity transfer to the deltapi* ? sigma* band. The anticipated Ru … Ru separation is of the order of 2.9 and 3.0 A for the mixed-valence AsMe3/mu-Cl and PMe3/mu-Cl systems respectively, markedly longer than the crystallographic value of 2.75 A in [(NH3)3Ru(mu-Cl)3Ru(NH3) 3]2+. The geometric distinction between the AsR3- and PR3-capped dimers is an unexpected consequence of selective crowding between the substituent R groups and the {mu-X3} array. The present Ru2II,III systems are electronically distinct from their PR3-containing osmium counterparts, such as [(Et3P)3Os(mu-Cl)3Os(PEt)3] 2+, which show still greater visible/near-infrared spectral deviations.

Geometrical isomerization of fac-Mo(CO)3L3 (L = P(OPh)3, P(OMe)3, P(OEt)3) to the mer form and that of cis-Mo(CO)4L2 (L = P(OPh)3, P(OMe)3, PPh2(OMe)) to the trans form were observed in CH2Cl2 at room temperature in the presence of a catalytic amount of Me3SiOSO2CF3 (TMSOTf). Crossover experiments suggest that a ligand dissociation is not involved in the isomerization. A catalytic cycle involving an interaction of the silicon atom in Me3Si+ with one oxygen in P(OR)3 ligands has been proposed. The first isolation and the X-ray structure analysis were attained for mer-Mo(CO)3{P(OPh)3}3 through the TSMOTf-assisted isomerization of fac-Mo(CO)3{P(OPh)3}3.

p-Methoxybenzoyldialkylphosphonates, where alkyl = methyl, ethyl and p-methoxy-benzoyldiphenylphosphine oxide were synthesized by Michaelis-Arbuzov reaction. These compounds were used as photoinitiators for radicalic polymerization of acrylic monomers. The photoreactivity parameters were determined by differential photocalorimetry (DPC), in isothermal conditions, using 1,6-hexandioldiacrylate (HDDA) as monomer, in the presence and absence of amine. The influence of concentration on film pendulum hardness was studied.
