 Title    Bor-stabilisierte N,0-Carbene, II [1] Röntgenstrukturanalyse von (fra/i5-4,5-Dimethyloxazolidin-2-yliden)triphenylbor und N-Alkylierungen Boron Stabilized N,0-Carbenes, II [1] X-Ray Structure of (/rans-4,5-Dimethyloxazolidin-2-ylidene)triphenylboron and N-Alkylations  
 Abstract    The X-ray structure analysis of (?rartj,-4,5-dimethyloxazolidin-2-ylidene)triphenylboron reveals a stereochemistry of the carbene ligand which is almost identical with that in transition metal complexes. Deprotonation of triphenylboron stabilized oxazolidin-2-ylidenes with NaH leads to (oxazolin-2-ato)borates, which have been N-alkylated with [R30 +][BF4_] or R I under mild condi­ tions.

 Abstract    , II [1] Reaktionen von [M(CO)5CNH] (M = Cr, Mo, W) mit Aziridinen: Zyklische Diaminocarbenkomplexe Chemistry of Hydrogen Isocyanide, II [1] Reactions of [M(CO)5CNH] (M = Cr, Mo, W) with Aziridines: Cyclic Diaminocarbene Complexes The hydrogen isocyanide com plexes [M (C O)5CNH] (M = Cr, M o, W) have been treated with the aziridines R N C H R 'C H 2 (R = H, R' = H, Me, Et; R = M e, R' — H) to give im idazolidin-2-ylidene com plexes. The sam e type of ligand forms on addition of aziridine to the electrophilic isocyanide group in [FpC N Ph]+ in the presence of B r'. IR, 'H N M R , 13C N M R and mass spectra of the new com pounds are reported.
