1,2-Epoxy-5-hexene → Diphenylbis(5,6-epoxyhexyl)silane

Participants

Reaction Steps

27.6 g of diphenylsilane (0.15 mole) were dispersed in 100 g toluene with 0.02 g rhodiumtrichloride hydrate (as a solution in 0.5 cc ethanol) then the solution was brought to 100° C. when 32 g 1,2-epoxy-5-hexene (0.32 mole) were added dropwise. A two hour hold at 100°-110° followed, which consumed all SiH per IR analysis. Solvent was distilled off leaving 45 g residue as a mobile, 15 cstk viscosity fluid product, nD25 =1.5532. Infrared analysis was consistent with the proposed structure, with evidence of siloxane by products also present.
