Abstract
A process for the preparation of organosilicon compounds bearing silanol groups, in particular linear polyorganosiloxanes bearing lateral silanol groups, in a predictable manner and high yield, comprising reacting a similarly constructed Si—H functional organosilicon compound with water in the presence of a Group VIII metal catalyst, optionally in the presence of a cocatalyst. Predictable product structure and very few byproducts are particularly advantageous.
