Since the elucidation of the anti-Markownikoff addition of hydrogen bromide to alkenes as radical reaction 2,3) there has been a controversial discussion about factors governing regioselectivity and reactivity in free radical additions 4). Although the PMO-treatment of chemical reactivity 5,6)
## Abstract Ξ±β(Phenyltelluro)esters **2** reacted with electronβrich alkenes **3** in the presence of a catalytic amount of azobisisobutyronitrile (AIBN) as an initiator to give the corresponding addition products **4**. This carbotelluration of alkenes proceeded via a radical chain mechanism invol
## Abstract The title reaction leads to the compounds (III), (VI), (VIII), and (X) and suppresses the competing olefin polymerization.
