21. So a perfect citation graph is an example of a directed acyclic graph. 22. We call a mixed graph acyclic if all of its orientations are acyclic. 23. We call a mixed graph acyclic if all of its orientations are acyclic . 24. Deprotonated acyclic ethers perform beta-hydride eliminination, forming an olefinic ether. 25. The saturated heterocycles behave like the acyclic derivatives. 26. Acyclic allylic alcohols exhibit good selectivity as well.27. Angle strain typically affects cyclic molecules, which lack the flexibility of acyclic molecules. 28. Alternatively, one can build a binary acyclic problem directly from the decomposition tree. 29. The cycle decomposition method split a problem into a cyclic and an acyclic part. 30. Chiral acyclic alkenes also show diastereoselectivity upon reactions such as epoxidation and enolate alkylation.
