A novel method for catalytic remote bismetalation of alkene substrates by the addition of dimetal reagents is accomplished by using chain walking. In the presence of a palladium catalyst, the reaction of various 1,n-dienes and diborons were converted into cyclopentane derivatives with two boryl groups at remote positions via facile regioselective transformation of an unactivated sp3 C–H bond to a C–B
A polymer containing units represented by the defined formula (1); and a process for producing the polymer, which comprises the step of polymerizing a compound represented by the defined formula (3), the units represented by the formula (1) being polymerized units of the compound represented by the formula (3) such as 5,5-diallyl-2,2-dimethyl-1,3-dioxane.
