1-(2-trimethylsilylethyl)-1,1,3,3-tetramethyldisiloxane (18.8 g) and chloroplatininc acid catalyst (ethanolic solution, 30 ppm Pt) were charged to a 100 ml round-bottomed (RB) flask equipped with a magnetic stirrer, reflux condenser, and N2 inlet. The mixture was stirred and heated to 90° C. 2-Allyloxymethyl-oxirane (10 g) was placed in an addition funnel and added dropwise to the flask. The mixture was stirred and maintained at 90° C. for an additional 4 hours. Reaction progress was followed by NMR spectroscopy. Upon reaction completion, excess 2-allyloxymethyl-oxirane was removed by vacuum distillation.
