The absolute rate constants determined for the additions of FCPh, ClCPh, and BrCPh to Me2C=CMez, MepC=CHMe, trans-MeCH=CHEt, and n-BuCH=CH2 appear to follow a reactivity/selectivity pattern of the "normal" (inverse) type.
Absolute rate constants and their temperature dependencies were determined for the addition of hydroxymethyl radicals ( C H 2 0 H ) to 20 monoor 1,l-disubstituted alkenes (CH2 = C X Y ) in methanol by time-resolved electron spin resonance spectroscopy.
