Photoallylation and photoreduction of cyclohexylidenepropanedinitrile by use of allyltrimethylsilane via photoinduced electron transfer: control of the product ratio depending on pK(a) values of additives.
Irradiation of an acetonitrile solution containing cyclohexylidenepropanedinitrile (1) and allyltrimethylsilane (2) in the presence of phenanthrene afforded two kinds of allylated products (3, 4) and a reduction product (5). The product ratio of 3, 4, and 5 dramatically changed depending on the pK(a) values of additives.
