Abstract: Abstract An inexpensive, easily available, environmentally benign, and efficient catalyst molybdenum(VI) dioxo (acetylacetonate)2 was used for the direct oxo- and thioetherification of alcohol. This method endures selective molybdenum catalyzed dehydrative synthesis of symmetrical ethers from… read more here.

DOI: 10.1021/acs.orglett.2c03018
Abstract: Under mechanochemically induced conditions, a wide range of diarylphosphine oxides or H-phosphonates react with trisulfide dioxides to afford various thiophosphate derivatives in good yields. Selective S-S bond cleavage of trisulfide dioxides determined by connecting groups… read more here.
