✦ Synopsis

Improvements in the synthesis of g-bromo-difluoromethanimine, CF2=NBr. will be described along with some reaction chemistry. The imine undergoes thermal addition with a variety of olefins, leading to the simple addition product and to the formation of telomers. Photolysis with CO forms the isocyanate BrCF2tJ=C=0, in high yield. Pyrolysis of CF2=UBr at -450°C gives high yields of tetrafluoro-2,3-diara-1,3butadiene, CF24WJ=CF2. making this compound readily available for the first time. Some new reaction chemistry of the diene will be discussed.

## Abstract The present article gives an account of the synthesis and structure as well as the spectroscopic and chemical properties of arsaalkenes R^1^AsCR^2^R^3^ and arsaalkynes RCAs. Arsaalkenes are significantly less stable and more reactive than the corresponding phosphaalkenes. Only one kin
