相转移催化硝化四乙酰基二苄基六氮杂异伍兹烷

Nitration of Tetraacetyldibenzylhexaazaisowutzitane with Phase Transfer Catalysts

以相转移催化剂作为助溶剂,采用硝酸铈铵(CAN)和亚硝酸钠在氯仿中氧化TADBIW,在40℃下反应8小时,以66%的得率得到四乙酰基二硝基六氮杂异伍兹烷(TADNIW)。讨论了CAN相转移催化硝化的反应机理。

The nitration of tetraacetyldibenzylhexaazaisowutzitane by CAN and NaNO_2 in chloroform in the presence of phase transfer catalysts was kept for 8 hours at 40 ℃. The remained benzyl groups were nitrated successfully and the corresponding products-tetraacetyldinitrohexaazaisowutzitane was obtained with a yield of 66%. The mechanism of the nitration of N-benzyl group by CAN in the presence of phase transfer catalysts is discussed.
