Disclosed herein are embodiments of donor compounds that can be used to produce H.sub.2S from COS or CS.sub.2 released from the donor compounds. In some embodiments, the donor compounds can indirectly produce H.sub.2S after being exposed to a reactive component in a triggering event. In other embodiments, the donor compounds can indirectly regenerate H.sub.2S after reacting with an H.sub.2S analyte. The donor compounds disclosed herein can be used for analytical techniques, disease diagnostics, and/or therapeutic applications. Methods of making and using the donor compounds also are provided herein.

The present invention provides a method for fixing carbon dioxide gas as a carbonyl compound represented by formula (3) as depicted by FIG. 1 and comprising, purging of carbon dioxide in a solution of a nucleophile represented by the formula (1) in presence of a solvent at a temperature ranging from 40 Degree Celsius to 35 Degree Celsius, followed by adding a reagent at temperature ranging from 40 degree to 35 degree and thereafter adding another nucleophile represented by the formula (2) to obtain carbonyl compound represented by formula (3). The present invention can be advantageously used to obtain commercially important carbonyl compounds and clean unwanted carbon dioxide gas from the atmosphere and industrial effluents.
