    Notes: Summary The synthesis of the valuable terpenic synthon 2-acetyl-3,3-dimethylbicyclo[2.2.1]hept-5-ene is clearly improved concerning the yield and especially the reaction time by applying ultrasound on theDiels-Alder reaction of cyclopentadiene with mesityl oxide. A new synthesis of dehydrocamphene and its odour impression is described.

    Description / Table of Contents: Nitrosylthiocyantes of iron, cobalt and nickel are formed by the reaction of metal nitrosyl halides with potassium or silver thiocyanate. Similarly to these compounds, the nitrosylaryl and nitrosylalkyl mercaptides are obtained. They react with tertiary organic phosphines, arsines and stibines (L) as well as with o-phenanthroline (L2) forming the complexes M(NO)2LR (M = Fe, Co; R = NCS, SC6H5, SC2H5), [Ni(NO)LR]2 and Ni(NO)L2R (R = SCN, NCS, SC6H5).
    Notes: Nitrosylrhodanide der Eisenmetalle können durch Umsetzung der entsprechenden Nitrosylhalogenide mit Kalium- bzw. Silberrhodanid dargestellt werden. Auf gleiche Weise erhält man die bereits bekannten Nitrosylaryl- und Nitrosylakylmercaptide dieser Elemente. Das komplexchemische Verhalten dieser Verbindungen schließt sich weitgehend dem der entsprechenden Nitrosylhalogenide an: mit Organylen des Phosphors und seiner Homologen (L) und mit o-Phenanthrolin (L2) entstehen Komplexe der Typen M(NO)2LR (M = Fe, Co; R = NCS, SC6H5, SC2H5), bzw. [Ni(NO)LR]2und Ni(NO)L2R (R = SCN, NCS, SC6H5).

    Description / Table of Contents: The reaction of tetrameric nitrosylnickel halides with phosphines, arsines, stibines and amines (L) leads to nonpolar dimeric diamagnetic complexes [Ni(NO)(L)hal]2. The cis and trans stereo isomeres were isolated with tricyclohexyl phosphine as a ligand. In a second step of the reaction, the halogenobridges of this compounds are cleaved by addition of a second ligand.
    Notes: Die tetrameren Nitrosylnickelhalogenide [Ni(NO)Halg]4 geben mit Organylen des dreiwertigen Phosphors und seiner Homologen und mit Aminen (L) zunächst dimere diamagnetische, unpolare Komplexe [Ni(NO)(L) Halg]2; mit Tricyclohexylphosphin als Liganden konnten sogar die beiden cis-trans-Isomeren isoliert werden. Die Halogenobrücken dieser Verbindungen werden im weiteren Reaktionsablauf unter Addition eines zweiten Liganden aufgespalten.
