Thioketal ros

In organosulfur chemistry, a thioketal is the sulfur analogue of a ketal (R2C(OR)2), with one of the oxygen replaced by sulfur (as implied by the thio- prefix), giving the structure R2C(SR)OR. A dithioketal has both oxygens replaced by sulfur (R2C(SR)2). Thioketals can be obtained by reacting ketones (>C=O) or aldehydes (−CH=O) with WebApr 11, 2024 · The ROS-responsive degradable Fe-MOF was first synthesized through hydrothermal reaction composed of 2,2'-[propane-2,2-diylbis(thio)]diacetic acid as ROS-sensitive agent thioketal (TK) and Fe 2+ ion. Subsequently, GOX as exogenous H 2 O 2 supplier and starvation inducer and PFC as O 2 provider are co-loaded into Fe-MOF. …
