Derivatives

allylic

adjective əˈlɪlɪk

Chemistry

An example that Blackmond often uses is the asymmetric hydrogenation of the allylic alcohols geraniol and its isomers (g geraniol and nerol) carried out while she was at Merck.
Example sentencesExamples
- For substances containing allyl or allylic side chains a direct mechanism of action involving an allylic cation which then reacts with nucleophilic centers of nucleic acid bases has been discussed in the literature.
- Abstraction of the double allylic hydrogen of CDH by triplet BZP would lead to a radical pair; this could explain the formation of benzene and all the detected minor photoproducts.
- Decomposition of these primary photoproducts to give secondary products arising from allylic hydroperoxide degradation - either by Hock rearrangement or by alkenyl ether epoxidation - was also observed.
- In complementary experiments, CHD and CHDCA were used as models for LA as they also have double allylic systems.

Origin

Mid 19th century: from Latin allium 'garlic' + -yl.
