title: Highly ordered acid functionalized SBA-15: a novel organocatalyst for the preparation of xanthenes.
abstract: Post-synthesis modification of SBA-15 has been carried out to design highly ordered acid functionalized hybrid mesoporous organosilica, AFS-1. This material has been used as an efficient heterogeneous organocatalyst for the syntheses of xanthenes under mild conditions in the absence of any other metal co-catalyst.
