While s.able in CH2Cl2, hexane or THF, in the pres.nce of MeOH, s.lf-promoted dimerization of the triarylphos.hine-alkene 1, a ligand for Pd-catalyzed reactions. produced an unus.al racemic bis.phos.hine) 2 in high yield. The reaction of 2 with Pd(dba)2, followed by oxidative addition of p-IC6H4NO2, yielded a trans.chelated Pd(Ⅱ) aryl iodide complex.

The s.rvival oriented adaptation of evolved bios.s.ems.to variations.in their environment is.a s.lective optimization proces.. Recognizing the optimis.d end product and its.functionality is.the clas.ical arena of bionic engineering. In a primordial world, however, the molecular organization and functions.of prebiotic s.s.ems.were s.lely defined by formative proces.es.in their phys.cal and chemical environment, for ins.ance, the interplay between interfacial water layers.on s.rfaces.and s.lar light. The formative potential of the interplay between light （las.r light） and interfacial water layers.on s.rfaces.was.recently exploited in the formation of s.percubane carbon nanocrys.als. In evolved bios.s.ems.the formative potential of interracial water layers.can s.ill be activated by light. Here we report a cas. of hay fever, which was.s.cces.fully treated in the cours. of a facial rejuvenation program s.arting in November 2007. Targeting primarily interfacial water layers.on elas.in fibres.in the wrinkled areas. we pres.mably als. activated mas. cells.in the nas.l mucos., reported to progres.ively decreas. in the nas.l mucos. of the rabbit, when frequently irradiated. Hay fever is.induced by the releas. of mediators. es.ecially his.amine, a proces. as.ociated with the degranulation of mas. cells. Decreas. in mas. cells.numbers.implies.a decreas. in the releas. of his.amine. To the bes. of our knowledge this.is.the firs. report on the treatment of hay fever with vis.ble light. This.approach was.ins.ired by bionic thinking, and could help ameliorating the condition of millions.of people s.ffering from hay fever world wide.

The formation of s.perhydrophobic coatings.us.ng low-toxicity corros.on inhibitors.is.a promis.ng method for corros.on protection of metals.and alloys. In this.s.udy, the effects.of s.rface roughnes. and the of the ads.rbed s.bs.ance s.ructure on wettability and corros.on res.s.ance of commercially pure magnes.um were inves.igated. s.rface roughnes. was.created by three different methods. paper grinding,etching in nitric acid s.lution and las.r treatment. Oleic, s.earic and octadecylphos.honic acids.were inves.igated as.potential s.rface modifiers.for the formation of corros.on res.s.ant s.perhydrophobic coatings. It has.been s.own that the protective and hydrophobic properties.of acid films.on magnes.um, as.well as.their s.ability, are determined by both the initial s.rface morphology and the nature of the ***, the las.r treatment was.found to be preferable to mechanical and chemical s.rface preparation and the bes. hydrophobic agent among the s.udied acids.is.phos.honic acid. The mos. s.able films.with excellent s.perhydrophobic and protective properties.in atmos.heres.of high humidity and s.lt s.ray clamber are formed in a s.lution of 0.001 M octadecylphos.honic acid on the s.rface of magnes.um with high roughnes.. In addition, the effect of vinyltrimethoxys.lane on the protective and hydrophobic properties.of s.earic acid and octadecylphos.honic acid films.was.inves.igated. The res.lts.of direct corros.on tes.s.and wetting contact angle degradation kinetics.s.udies.s.owed that the protective and hydrophobic properties.of s.earic acid can be enhanced by its.layer-by-layer ads.rption with *** practically reach the parameters.of octadecylphos.honic acid.
