The thermodynamic properties of four triphenylsilane acetylene peroxides

The enthalpies of formation of four acetylene triphenylsilane peroxides were determined in the condensed and gaseous states. Three silicon-containing fragment increments for the Benson additive scheme and the enthalpies of formation of three radicals formed in the dissociation of the compounds at the O-O bond were calculated.
