Novel compounds comprising a C—C double bond substituted at one carbon with two oxygen or sulfur atom-containing groups are disclosed. The compounds are useful in methods and compositions for generating chemiluminescence by reaction with a peroxidase enzyme and a peroxide. The chemiluminescence thus produced can be used as a detectable signal in assays for peroxidase enzymes and in assays employing enzyme-labeled specific binding pairs.

Chiral ligands and transition metal complexes based on such chiral ligands useful in asymmetric catalysis are disclosed. The chiral ligands include chiral C1-C6 TunaPhos ligands. The ruthenium TunaPhos complex reduces ketones to the corresponding alcohols with 95-99.6% enantioselectivity. The transition metal complexes of the chiral ligands are useful in asymmetric reactions such as asymmetric hydrogenation, hydride transfer, hydrosilylation, hydroboration, hydrovinylation, hydroformylation, hydrocarboxylation, isomerization, allylic alkylation, cyclopropanation, Diels-Alder reaction, Heck reaction, isomerization, Aldol reaction, Michael addition and epoxidation reactions.
