| Popis: | The preparation of α,ω-diynes with methyl groups at the termini (lla-i) is described. The methylene groups between the alkyne units vary between n = 12 (a) and n = 4 (i). Ring closing metathesis with Mo(CO) 6 /CF 3 C 6 H 4 OHyielded the monocyclic alkyne 12a with 11a as starting material, whereas 11b-g yielded the cyclic diynes 13b-g. Detailed structural parameters were obtained for 13b and 13c by X-ray crystallography. |
