実験手順

A mixture of 30.84 g of bis(3-(trimethoxysilyl)propyl)amine (0.0903 mol) and of 13.68 g of diisopropylcarbodiimide (0.1084 mol, 20% excess) was heated for 31 h at 110° C. (amine conversion of 94%). The final colorless mixture was devolatilized at 100° C. under 2 mbar for 2 h to give 42 g of a colorless, low-viscosity liquid corresponding to the expected guanidine, containing 4% of the initial amine.
