A malic acid or oxalacetic acid derivative is represented by the following formula (1):
1
wherein ring Z is an alicyclic carbon ring; each of R
a
and R
b
is independently a hydrogen atom, a metal atom, or an organic group; and Y is a hydroxyl group or an oxygen atom, where ring Z is a bridged carbon ring or a monocyclic carbon ring having eight or more members when Y is an oxygen atom. The alicyclic carbon ring includes, for example, cyclooctane ring and adamantane ring. This compound is a novel malic acid derivative having an alicyclic group bonded to a carbon atom at the 3-position, or a novel oxalacetic acid derivative having a specific alicyclic group bonded to a carbon atom at the 3-position.
oxyalkylated products in 91% yield. Other alkenes such as fumarate and acrylonitrile also serve as good acceptors of alkylradicals and O(2) to afford the corresponding adducts in high yields. The generality of the present reaction was examined between various alkanes and alkenes under dioxygen. The behavior of Co ions during the reaction course was discussed. The present reaction involves (i) an alkyl radical
