Abstract
Abstract Novel terpenoid alkoxysilanes having the general formula: ##STR1## wherein Y is hydrogen or Si(R 2 ) n X m (OR 3 ) 3- (N-m), Z is hydrogen or Si(R 2 ) n X m (OR 3 ) 3- (n+m), one of Y and Z being Si(R 2 ) n X m (OR 3 ) 3- (n+m), R 2 and R 3 being the same or different C 1 -C 3 alkyl group, X is halogen, m and n are independently selected from 1 and 0, and II W is Si(R 2 ) n X m (OR 3 ) 3- (n+m), where R 2 , R 3 , X, n and m are as defined above.
