    Description / Table of Contents: Preparation and Properties of 3-(N,N-Dimethylamino)propyl Thallium CompoundsTlCl3 reacts with Me2NCH2CH2CH2Li in molar ratio 1:2 with formation of (Me2NCH2CH2CH2)2TlCl (1) which can be transfered with MeLi into (Me2NCH2CH2CH2)2TlMe (2) and with excess of Me2NCH2CH2CH2Li into (Me2NCH2CH2CH2)3Tl (3) respectively. Comproportionation of 1 with TlCl3 yields rather instable Me2NCH2CH2CH2TlCl2 (4) from which Me2NCH2CH2CH2TlMe2 (5) can be obtained by alkylation with MeLi. 1-3 and 5 were characterized by elemental analysis, mass spectra, 1H- and 13C-n.m.r. spectra.
    Notes: TlCl3 reagiert mit Me2NCH2CH2CH2Li im Molverhältnis 1:2 zu (Me2NCH2CH2CH2)2TlCl (1), welches mit MeLi in (Me2NCH2CH2CH2)2TlMe (2) und mit weiterem Me2NCH2CH2CH2Li in (Me2NCH2CH2CH2)3Tl (3) übergeht. Bei der Komproportionierung von 1 mit TlCl3 entsteht das wenig stabile Me2NCH2CH2CH2TlCl2 (4), das in situ mittels MeLi in das beständige Me2NCH2CH2CH2TlMe2 (5) übergeführt werden kann. Die 1H- und 13C-NMR-Spektren von 1-3 sowie 5 werden mitgeteilt und die Strukturverhältnisse diskutiert.

    Description / Table of Contents: The 3-(N,N-Dimethylamino)prop-1-enyl Group as a Chelate Ligand in Indium OrganylsInBr3 reacts with Me2NCH2CH=CHMgCl (molar ratio 1 : 2) to form (Me2NCH2CH=CH)2InBr (1) as the first indium alkenyl compound with amino-functionalized alkenyl groups. The X-ray structure determination shows the formation of a chelate complex. 1 crystallizes in the orthorhombic space group Fddd with the unit cell parameters a = 14.904(2) Å, b = 17.140(1) Å and c = 21.035(2) Å. By reaction of Me2InBr with Me2NCH2CH=CHMgCl (molar ratio 1 : 1) (Me2NCH2CH=CH)InMe2 (2) is formed as a colorless, at room temperature liquid, monomeric compound. The n.m.r. and mass spectra are discussed.
    Notes: InBr3 reagiert mit Me2NCH2CH=CHMgCl (Molverhältnis 1 : 2) in Diethylether als Lösungsmittel zu (Me2NCH2CH=CH)2InBr (1), der ersten Indium-Alkenylverbindung mit aminofunktionalisierten Alkenylresten. Die Röntgenkristallstrukturanalyse zeigt das Vorliegen eines Chelatkomplexes an. 1 kristallisiert orthorhombisch in der Raumgruppe Fddd mit Z = 16, a = 14,904(2) Å, b = 17,1405(14) Å und c = 21,035(2) Å. Aus Me2InBr und Me2NCH2CH=CHMgCl (Molverhältnis 1 : 1) wurde (Me2NCH2CH=CH)InMe2 (2) als farblose, bei Raumtemperatur flüssige, monomere Verbindung erhalten. Die 1H- und 13C-NMR-Spektren sowie Massenspektren werden mitgeteilt.

    Description / Table of Contents: Preparation and Structure of Li[(Me2NCH2CH2CH2)4Yb]YbCl3 reacts with dimethylaminopropyl lithium in tetrahydrofuran with formation of Li[(Me2NCH2CH2CH2)4Yb]. The X-ray structure determination proves the formation of chelat rings by two of the ligands. The nitrogens of the other two ligands are coordinated to the lithium. The compound crystallizes in the monoclinic space group C2/c with the unit cell parameters a = 27.854(8) Å, b = 9.183(3) Å, c = 20.125(8) Å, β = 96.40° and Z = 8.

Die Röntgenkristallstrukturanalyse zeigt die Ausbildung von Chelatringen durch zwei der Liganden, während die Stickstoffe der anderen beiden Liganden am Lithium koordinativ gebunden sind. Die Verbindung kristallisiert monoklin in der Raumgruppe C2/c mit Z = 8, a = 27,854(8) Å, b = 9,183(3) Å, c = 20,125(8) Å, β = 96,40°.
