Krompiec, Stanis?aw,Pigulla, Mariola,Krompiec, Micha?,Baj, Stefan,Mrowiec-Bia?oń, Julita,Kasperczyk, Janusz
, p. 5257 - 5261 (2004)
A highly selective rhodium and ruthenium catalyzed transformation of N-allylamines and N-allylamides to the corresponding 1-propenyl derivatives is described. Strong E-selectivity in the isomerization of allylamines was observed. The first catalytic syste

, p. 2060 - 2061 (2003)
A novel route to enamines is reported, the dehydrogenation of tertiary amines catalyzed by a "pincer-ligated" iridium catalyst.
Synthesis of 5-aminoisoxazolines from N-allyl compounds and nitrile oxides via tandem isomerization-1,3-dipolar cycloaddition

experimental part, p. 5972 - 5981 (2010/09/18)
A new strategy for the synthesis of derivatives of 5-aminoisoxazolines via tandem catalytic isomerization (of N-allyl systems to N-(1-propenyl) systems) - 1,3-dipolar cycloaddition (of a stable nitrile oxide to N-(1-propenyl) systems) is presented. Rhodiu
Convenient synthesis of isoxazolines via tandem isomerization of allyl compounds to vinylic derivatives and 1,3-dipolar cycloaddition of nitrile oxides to the vinylic compounds
Krompiec, Stanis?aw,Bujak, Piotr,Szczepankiewicz, Wojciech

A novel effective method for the synthesis of new isoxazolines via tandem isomerization of QCH(X)CH{double bond, long}CH(Y) to QC(X){double bond, long}CHCH2(Y) (Q = RO, RS, R2N, R3Si, etc.; X = H, R, OR; Y = H, R; R = alkyl, aryl) catalyzed by ruthenium complexes and 1,3-dipolar cycloaddition of the latter compounds to arenenitrile oxides is presented. The cycloaddition of QCH(X)CH{double bond, long}CH(Y) to 2,6-dichlorobenzonitrile oxide is also described. The regio- and stereoselectivity of the cycloaddition of nitrile oxide to allyl and 1-propenyl (vinylic in general) compounds is discussed.
Organomagnesium Inner Complexes, Part I. Bis(dialkylaminoalkyl)- and Bis(alkoxybutyl)magnesium Compounds
Angermund, Klaus,Bogdanovic, Borislav,Koppetsch, Gudrun,Krueger, Carl,Mynott, Richard,et al.
, p. 455 - 466 (2007/10/02)
A series of magnesium inner complexes has been prepared by reacting MgH2 (prepared by homogeneous catalysis) with dialkylallyl- and -3-butenylamines and -3-butenylethers in the presence of catalytic amounts of ZrCl4.The monomeric nature of bis(4-methoxybutyl)magnesium has been confirmed by X-ray diffraction.The analogous syntheses of bis(3-alkoxypropyl)magnesium compounds failed: cleavage of the allyl ether with elimination of propene occurred.This cleavage reaction is accelerated by catalytic amounts of NiCl2 or ZrCl4. - Keywords: Magnesium, Inner Complexes, Crystal Structure, X-Ray
