MECHANISM OF THE CONTROLLED HYDROLYSIS OF (NPCL2)(2)NSOCL - CRYSTAL AND MOLECULAR-STRUCTURE OF [KC12H24O6](+)[NHPO2NPCL2NSOCL](-)

Autor: WINTER, H, MEETSMA, A, VANDEGRAMPEL, JC, SPEK, AL

Publikováno v: Heteroatom chemistry, 5(4), 343-348

The reaction mechanism of controlled hydrolysis of the inorganic ring system (NPCl2)(2)NSOCl in the presence of KCl and 18-crown-6 has been revised and is explained from steric constraints rather than from electronic considerations. The X-ray structu
