The reaction of [C6H6Ru(PiPr3)Cl2] (1) with NaONCRR′ in the presence of KPF6 leads to the formation of the oximatoruthenium(II) complexes [C6H6Ru(η2-ONCRR′)(PiPr3)]PF6 (2–5) in 70–90% yield. Compound 5 (R Me, R′ tBu) reacts with HNCPh2 via ligand exchange to give [C6H6Ru(NCPh2)(Pi Pr3)]PF6 (8). The azavinylidene complex 8 has also been prepared from the acetatoruthenium derivative [C6H6Ru(η2-O2
在KPF 6存在下,[C 6 H 6 Ru(P i Pr 3)Cl 2 ](1)与NaONCRR'的反应导致形成氧亚氨基钌(II)络合物[C 6 H 6 Ru( η 2 -ONCRR')(P我镨3)] PF 6(2 - 5)在70-90%的产率。化合物5(RMe中,R'吨卜)与HNCPh发生反应2通过配体交换,得到[C 6 H ^ 6的Ru(NCPh 2)(Pi Pr 3)] PF 6(8)。所述azavinylidene复杂8也被从acetatoruthenium衍生物制备[C 6 H ^ 6的Ru(η 2 -O 2 CCH 3)(P我镨3)] PF 6(6),其可以或者从可以得到1,CH 3 CO 2 Na和KPF 6或从治疗的5用过量的CH 3 CO 2 H的hexamethylbenzeneruthenium化合物的合成[C6我6的Ru(NCR' 2)PR 3 ])PF

Displacement of fluorine from pentafluoropyridine under conditions by sodium oximates RR′CNO–Na+[R,R′= Me or Ph; R = Me, R′= Ph (anti isomer)] suspended in benzene or diethyl ether yields O-tetrafluoropyridyl oximes arising from monosubstitution at both 2- and 4-positions.
在肟酸钠RR'C NO – Na + [R,R'= Me或Ph的条件下,由五氟吡啶置换氟。R = Me,R′= Ph(反异构体)]悬浮在苯或二乙醚中,由于在2-和4-位单取代而产生O-四氟吡啶基肟。
Synthesis and some reactions of tris (pentafluorophenyl) antimony compounds
Abstract (C6F5)3Sb has been found to react with interhalogens and halo-pseudohalogens, IX(X = Cl, Br, N3 and NCO), pseudohalogen (SCN), and elemental sulphur to give oxidative addition products (I–VI). (C6F5)3SbS(VI) may also be prepared by the reaction of (C6F5)3SbCl2 with H2S. Metathetical reactions of (C6F5)3SbCl2 with appropriate metallic salts yield covalent pentacoordinate disubstituted products

The mechanism of the BECKMANN rearrangement and the fragmentation of ketoximes 1 has been studied by determining rate constants and products in «80%» ethanol of several anti-alkyl-, -cycloalkyl-, -aralkyl- and -phenyl-ketoxime tosylates with stationary syn-methyl and -phenyl substituents. The ratio of fragmentation to amide formation is not related to reaction rate, but increases with the stability
