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

Pyrex-filtered photoirradiation with a high-pressure Hg lamp was performed for a thermally inert hydridocobalt(I) CoH4 in the presence of some allylic compounds.Allyl benzoate and allyl phenyl ether showed the cleavage of allylic-O bonds to give propene in a stoichiometric quantity to the complex charged.Photoassisted catalytic double-bond migration occured for N-allylacetamide, N,N-diethylallylamine, and allylbenzene to afford the respective (E)- and (Z)-1-propenyl derivatives with kinetically controlled, E, Z compositions, and the fractions of Z isomers at the initial stage of the reaction proceeding were near 79, 30, and 20percent, respectively.Laser flash photolysis study revealed that the double-bond migration was initiated by the coordination of the substrates through C=C double bond rather than nitrogen or oxygen donor-atom to the coordinatively unsaturated species "CoH3" photogenerated.
