Abstract
Grace-Davidson silica pellets (SMR-057-015) are found to be optimal for surface grafting of (RO)3Si(CH2)3FG reagents. While loadings of up to 2.1 mmol g−1 can be attained (ca. 0.05 mmol per pellet) access of further reagents to the graft sites is problematic above loadings of 0.8 mmol g−1. 13C CPMAS NMR studies may be carried out on individual pellets (using natural abundance substrates) and the resulting spectra are diagnostic in identifying successful subsequent coupling reactions.
Sequential synthesis can be attained on mesoporous silica pellets and monitored by solid-state 13C NMR spectroscopy.
