METHOD OF ACYLATION OF HEXAKIS(PHENYLMETHYL)HEXAAZAISOWURZITANE Russian patent published in 2002 - IPC

FIELD: chemical technology. SUBSTANCE: invention describes method of acylation of hexakis(phenylmethyl)hexaazaisowurzitane of the formula (I): WB₆ where B means phenylmethyl and W means residue of hexavalent hexaazaisowurzitane presented by the formula (2): by reductive dephenylmethylation including contact of hexakis(phenylmethyl)hexaazaisowurzitane with a heterogeneous catalyst of reduction in the presence of acylating agent and reducing agent in solvent for the indicated hexakis(phenylmethyl)hexaazaisowurzitane characterizing that the contact of WB₆ with heterogeneous reductive catalyst is possible only the presence of both reagents: acylating agent and reducing agent to yield a mixture containing at least one derivative of tetraacylhexaazaisowurzitane of the formula (3): WA₄B_nH_(2-n), where W and B are determined above; H means hydrogen atom; A means C_1-C₁₀-acyl group; n = 0-2. EFFECT: stably high yield of end products, effective inhibition of decomposition of hexaazaisowurzitane skeleton. 5 cl, 4 dwg, 8 tbl, 21 ex
