In many addition reactions, 1 is much more reactive than normal olefins. Thus 1 adds alcohols and water (the latter in THF as cosolvent) at 50" C without catalysis to give the adducts 6 and adds ketones in a thermal reaction yielding the 1, 2-disilaoxetanes 7.8, 9 With oxygen, 1 is converted to the 1, 3-dioxetane SI0 in a reaction reminiscent of ozonolysis of olefins. Compound 8 appears to be the first example of a cyclodisiloxane. Compound 1 is ...
