 Title    Triplett-sensibilisierte Isomerisierung des Insektizids Thiodan Triplet Sensibilized Isomers of the Insecticide Thiodane  
 Abstract    The photoisomerization reactions of cyclodiene insecticide Thiodane were investigated in dif-ferent solvent systems, with wavelengths above 290 nm. The results show that /S-isomere (2) can be converted in the presence of acetone into the a-isomere (1). Photokinetic experiments give sufficient information on the character of the excited state of these compounds.

 Title    Darstellung von "Nitrenkomplexen" via Säureazide und Azidosäureester Synthesis of "Nitrene Complexes" via Acid Azides and Azido Acid Esters  
 Abstract    The photochemical reaction of carboxylic acid azides and azido carboxylic acid esters, respectively, with ^ 5 -C5H5Mo(CO)3CH3 in CH2CI2 seems to be a general route to the nitrene bridged complexes ^ 5 -C5H5(0 =)M0-iu(0)-(u(NC0R)M0(= 0)-r? 5 -C5H5 and ^-C5H5(0 -)Mo-/I(0)-/*(NC00R)Mo(-OJ-TJÖ-CSHS.

 Title    Photochemische Reaktionen von Übergangsmetall-Organyl-Komplexen mit Olefinen, VI [1] Reaktionen von Tricarbonyl-T]5-2,4-cyclohexadienyl-mangan mit konjugierten Dienen Photochem ical Reactions of Transition Metal Organyl Complexes with Olefins, VI [1] Reactions o f Tricarbonyl (^5-2,4-cyclohexadienyl)manganese with Conjugated Dienes  
 Abstract    Tricarbonyl-?/5-2,4-cyclohexadien-l-yl-manganese (1) was reacted photochemically at 253 K with simple conjugated dienes. Four different types of products were obtained, depending upon the dienes. With 1,3-butadiene (A) dicarbonyl-743-l-(3-buten-l,2-diyl)-2,4-cyclohexa-diene-manganese (2 A) is isolated. 2-Methyl-1,3-butadiene (B) yields the methyl-substituted diastereomeric dicarbonyls 2B, 2B', the [4+5]-cycloadduct tricarbonyl-//3:2-3-methyl-bicyclo-[4.3. l]-3,8-decadien-7-yl-manganese (3B) and tetracarbonyl-?/3-4-methylene-bicyclo[4.3. l]-8-decen-3-yl-manganese (4B) with an exocyclically coordinated tetracarbonylm anganese frag­ ment. W ith 2,3-dimethyl-1,3-butadiene (C) only the [4+5]-cycloadduct 3C and the tetracar-bonyl 4C are obtained. No CC-bond formation is observed with ^,^-2,4-hexadiene (D) and 1,3-cyclohexadiene (E). Carbonyl-75-2,4-cyclohexadien-1 -yl-74-£,> £'-2,4-hexadiene-manganese (5D), and carbonyl-74-l,3-cyclohexadiene-^5-2,4-cyclohexadien-l-yl-manganese (5E) are the only products. The complexes were separated and purified by HPL chrom atography. Their constitutions were determined by IR and N M R spectroscopy.

 Title    Attack by a Lithiated Aminofluorosilane on the C-0 Bond of Cr(CO)6; Formation of Isonitrile Complexes  
 Abstract    The photochemical reaction of a lithiated aminofluorosilane with Cr(CO)6 leads to sub-stitution of one or two carbonyl oxygen atoms and formation of isonitrile complexes. The crystal structure of the disubstituted product, cis-di(<er£-butyhsonitrile)tetracarbonylchromium, has been determined.
