For example, from a solution of tetrachloroauric acid, the oxonium ion [H 7 O 3] + has been isolated as the salt [(H 7 O 3)(15-crown-5) 2][AuCl 4]. Neutron diffraction studies revealed a sandwich structure, which shows a chain of water with remarkably long O-H bond (1.12 Å) in the acidic proton, but with a very short OH•••O distance (1. ...

3 CH 2 O + 3 H 2 NMe → (CH 2 NMe) 3 + 3 H 2 O. The C-substituted derivatives are obtained by reaction of aldehydes and ammonia: [1] 3 RCHO + 3 NH 3 → (RCHNH) 3 + 3 H 2 O. 1-Alkanolamines are intermediates in these condensation reactions. [2] RDX, an explosive, is a hexahydro-1,3,5-triazine. The parent hexahydro-1,3,5-triazine (CH 2 NH) 3 ...
