 Title    and their [M-CH3] + Fragments  
 Abstract    In contrast to the corresponding butyl ions the [M-CH3]+ ions from isomeric pentyl-benzenes do not isomerise completely to a mixture of interconverting structures prior to decomposition.

 Title    Oberflächenverbindungen von Übergangsmetallen, XX [1] Komplexe von Oberflächen-Chrom(II) mit Olefinen Surface Compounds of Transition Metals, XX [1] Complexes of Surface Chromium(II) with Olefines  
 Abstract    Surface chromium(II) supported on silica forms 1:1 and 1:2 complexes with defines; polyenes prefer chelate structures. For the ligand-to-metal bond a "Zeise-Salt" type is postulated. Secondary reactions include cis-trans isomerisation, shift of double bond, rearrangement of C-framework and polymerization/oligomerization. Cyclopentadiene obviously gives a h 5 -cyclopentadienyl/hydrogen complex by oxidative addition followed by H2 emission and formation of a h 5 -cp-Cr m complex; in this case the metal can be split off from the support by H+ without cleavage of the cp-Cr-bond.
