L-Bromo-2-phenylethylene

Esters can be obtained from halogenated olefins using a metal carbonyl catalyst (87), eg, /n j -l-bromo-2-phenylethylene is treated with nickel carbonyl in the presence of methanol to afford the corresponding methyl cinnamate (see Cinnamic acid). 

Treatment of l-bromo-2-deuterio-2-phenylcthane with strong base leads to a mixture of deuterated and nondeuterated phenylethylenes in an approximately 7-.1 ratio Explain. 

Bromine and acetic acid added to a soln. of l-methylsulfinyl-l-methylthio-2-phenylethylene in acetic acid, and stirred 17.5 hrs. at room temp. a-bromo-phenylacetic acid. Y 73%. F. e. s. K. Ogura, S. Furukawa, and G. Tsuchihashi, Bull. Chem. Soc. Japan 48, 2219 (1975).
