 Title    Konkurrenzreaktionen einiger tricyclischer Diene zur [2 2]PhotocycIoaddition Competitive Reaction of Some Tricyclic Dienes to [2+2]Photocycloaddition  
 Abstract    The UV-behaviour of some chlorinated tri-cyclic dienes (la-e) was studied in acetone. Cycloaddition (2a-b and 2d-c), hydrogen-transfer (3c' and 3d) and photo ene-(3c)-reaction products could be isolated and identified with the help of spectroscopic methods.

 Title    Zur Synthese von 2.5-und 2.6-verbrückten Tetrahydromethanoindanen Synthesis of 2,5-and 2,6-Crosslinked Tetrahydromethanoindanes  
 Abstract    A direct synthetic method for some 2,5-and 2.6-crosslinked chlorinated tetrahydromethano-indanes, which are the most important conver-sion products of cyclodiene insecticides under abiotic conditions, is described. The structures of the resulting compounds are confirmed with the aid of MS and m NMR.

 Title    The UV Photolysis (x = 185 n m ) o f Liquid Methyl rc-Propyl Ether  
 Abstract    H e i n z -P e t e r S c h u c h m a n n a n d Cl e m e n s v o n S o n n t a g Methyl The main products of the 185 nm photolysis of liquid methyl n-propyl ether (quantum yields in parentheses) are n-propanol (0.70), m ethane (0.29), «ec-butyl methyl ether (0.20), methanol (0.16), propionaldehyde (0.13), 3,4-dimethoxyhexane (0.09), ethane (0.08), and ethyl n-propyl ether (0.08). The quantum yields of further 24 minor products have been measured. The quantum yield of the sum of primary photochemical processes, the main ones of which are the homolytic scissions of the C -0 bonds (reactions i and ii), is close to unity.

 Title    Photodimerisation of Amidopyrine [1,2] An Example of [2-f-2] Photocycloaddition of an Enamine-Like Structure  
 Abstract    The photochemical behaviour of amidopyrine (1) in cyclohexane was studied. The photodimer (2) and three fragmentation products (3-5) could be isolated and identified with the help of spectroscopic methods. The participation of 4-pyrazolin-3-ones in photo-chemical cycloadditions is demonstrated for the first time.
