Acyclic stereoselection for 1,2-diol systems via vinyl acetal rearrangement: control of relative stereochemistry in the rearrangement of 2,2,4-trimethyl-1,3-dioxolan-4-yl prop-1-enyl ethers to 2,3-dimethyl-3,4-(isopropylidenedioxy)butanals
A method of treating textiles in order to increase the water absorptivity of the textiles involving contacting the textiles with an effective amount of a dioxolane functional organosilicon compound. Representative of the dioxolane or ketal functional organosilicon compounds employed are sym(2,2-dimethyl-4-methyloylpropyl-1,3-dioxolane) disiloxane and sym(2,2-dimethyl-4-methyloylpropyl-1,3-dioxolane) polydimethylsiloxane.
