Summary
-
1.
Five new organosilicon esters of organosilicon acids were prepared by the transacylation of trialkylsilyl propionates with mono- and di-basic organosilicon acids.
-
2.
For use as intermediaries we synthesized (diethylmethylsilyl)propionic acid, diethyl [(diethylmethylsilyl]methyl]malonate, and 3,3′-(tetraethyldisiloxanylene)dipropionic acid.
-
3.
It was shown that treatment of (diethylmethylsilyl)propionic acid with concentrated sulfuric acid at room temperature results in rupture of the CH3-Si bond and formation in good yield of 3,3′-(tetraethyldisilox-anylene)dipropionic acid.
