1H nuclear magnetic resonance of α-hexahydro-1,3,5-trinitro-s-triazine (RDX) and the α-, β-, γ- and δ-polymorphs of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX)

✦ Synopsis


H NMR spectra of the energetic materials a -h e x ~y d r o -1 , 3 , 5 -~~o -s -~~e (RDX) and the a-, 8-, yand S-polymorphs of octahydro-1,3,5,7-te~tro-l,3,5,7-tetrazocine (HMX) have been obtained in the solid phase. Primary and secondary dipole-dipole interactions can be observed, which allows calculation of the intramolecular H ---H distances. The spectra suggest that y-HMX, the molecular structure of which is unknown, possesses a chair-chair ring conformation similar to that of a-and S-HMX.

The natural and synthetic glucocorticoids are very important compounds commonly used as drugs against many diseases. Recently, we have reported the synthesis of some of the title compounds and their transformations into 6-methyl-5-androstene-3,11,17-trione 3-ethyleneacctal, a building block for the
