摘要

Parent oligo (cyclohexy1idenes) l (n)(n= 1-41 were synthesized using a modified Barton- Kellogg olefin synthesis. Surprisingly, the crude compounds l (2) and l (4) contained small amounts of the l (n-1) and l (n+ l) homologues. As evidenced by a close examination of mass spectral data of selectively deuterated tercyclohexylidenes 1 (2)-QQ and 1 (2). de, their formation can be attributed to scrambling of the intermediate azines. With increasing n, a ...
