摘要：

Heating aryl isocyanates in N,N-dimethylformamide produces the previously unreported pentaaryl-1,3,6,8,10-pentazaspiro [4.5] decane-2,4,7,9-tetraones 4. The formation of 4 involves N-aryl-N′-dimethylformamidines 1 as well as the 2:1 cycloadducts 2 of aryl isocyanates and 1 as intermediates. © 1968, American Chemical Society. All rights reserved.
