 Title    /?)MandeIonitrile and Prunasin, the Sources of Hydrogen Cyanide in All Stages of Paropsis atomaria (Coleoptera: Chysomelidae  
 Abstract    Mandelonitrile, Pruna­ sin (/?)Mandelonitrile and the cyanogenic glucoside prunasin have been established as the source of HCN in all stages of the Australian beetle Paropsis atomaria. Quantitative data for both compounds and all life stages are presented. The larvae contain a ß-glucosidase activity capable of hydrolysing prunasin and also ß-cyanoalanine synthase activity enabling the disposal of free cyanide.

 Title    Darstellung und Eigenschaften von 1.3.2-Dioxaborolandionen-(4.5) Preparation and Properties of l,3,2-Dioxaborolanediones-(4,5)  
 Abstract    2-Organo-l,3,2-dioxaborolanediones-(4,5) RBC204 (R = CHS , C2H5 , C6H5 , C6F5) are formed from anhydrous oxalic acid and dihalogeno-organo-boranes. The five-membered ring-compounds are strong Lewis acids. The thermal degradation yields CO, C02 , and organoboroxines (RBO) 3 .
