EPR and ENDOR spectroscopic study of the reactions of aromatic azides with gallium trichloride.
The reactions of gallium trichloride with phenyl and deuterio-phenyl azides, as well as with 4-methoxyphenyl azide and deuterium isotopomers, were examined by product analysis, CW EPR spectroscopy and pulsed ENDOR spectroscopy. The products included the corresponding anilines together with 4-aminodiphenylamine type dimers, and polyanilines. Complex CW EPR spectra of the radical cations of the d...
متن کاملDirect chlorination of alcohols with chlorodimethylsilane catalyzed by a gallium trichloride/tartrate system under neutral conditions.
The reaction of secondary alcohols 1 with chlorodimethylsilane (HSiMe(2)Cl) proceeded in the presence of a catalytic amount of GaCl(3)/diethyl tartrate to give the corresponding organic chlorides 3. In the catalytic cycle, the reaction of diethyl tartrate 4a with HSiMe(2)Cl 2 gives the chlorosilyl ether 5 with generation of H(2). Alcohol-exchange between the formed chlorosilyl ether 5 and the s...
متن کاملSynthesis of fluoranthenes by hydroarylation of alkynes catalyzed by gold(I) or gallium trichloride
Electrophilic gold(I) catalyst 6 competes with GaCl(3) as the catalyst of choice in the synthesis of fluoranthenes by intramolecular hydroarylation of alkynes. The potential of this catalyst for the preparation of polyarenes is illustrated by a synthesis of two functionalized decacyclenes in a one-pot transformation in which three C-C bonds are formed with high efficiency.
متن کاملBenzene-1,3,5-tricarbonyl trichloride
In the title molecule, C(9)H(3)Cl(3)O(3), there are three short interactions involving the benzene H atoms and the chloro-formyl Cl atoms. In the crystal, mol-ecules stack along the a axis with no significant non-bonded inter-actions.
متن کاملSolutions of Gallium Trichloride in Ethers: A 71 Ga NMR Study and the X-Ray Structure of GaCl3 • Monoglyme
Solutions o f G aC l3 in various ethers have been studied by 7lG a N M R spectroscopy. <S7lG a data indicate tha t the predom inant species in d iethylether and tetrahydrofuran solutions are G aC l3 0 (C 2H 5) 2 and G aC l3 -2 0 C 4 H g, respectively. However, in monoglyme solution disso ciation occurs and the product crystallizing from the solution is [c7's-G aCl2(m onoglym e)2]G aC l4 as dem...
