The reaction of di-t-butyl selenoketone with propiolic acid gave 2H,6H-1,3-oxaselenin-6-one in 78% yield, whereas the reaction of di-t-butyl thioketone with propiolic acid recovered the starting th...
synthesis of selenoketone-platinum complexes 3a-3c was achieved by reacting selenoketones 4 with (η 2 -ethylene)bis(triphenylphosphine)platinum(0) (1). 1,1,3,3-Tetramethylindan-2-selone-platinum complex 3b was determined by X-ray crystallographic analysis to be an η 2 -selenoketone-platinum complex. Interestingly, only one isomer of selenofenchone-platinum complex 3c was formed by this reaction.
reported. The reaction of dimagnesium salts of ketone hydrazones with diselenium dichloride affords an intermediate tentatively assigned as tetraselenides, which are converted into selenoketones by heating in the presence of tributylamine. A comparative study on the reactions of 1,1,3,3-tetramethyl-2-indanselone and the corresponding thioketone with Grignard and organolithium reagents have been carried
