The major products (11a-e) isolated from experiments using triyne and tetrayne precursors 10a-e, each having a different linker structure (ABC) from that in 5. Yields are for isolated, purified (SiO2) material. The nature of the ABC linker and the R group present in each precursor 10 can be deduced from the structure of each resultant product 11.
