Its beneficial widespread effect on health is attributed to sulphur compounds and particularly to thiosulfinates. Odorless and stable, alliin is the most abundant sulfur compound in whole, unbruised Garlic. When the clove of garlic is cut or crushed, the enzyme alliinase is released from its compartment and transforms S-allyl-L-cysteine sulfoxide or alliin into diallyl thiosulfinate allicin, the characteristic compound of garlic flavor. This very unstable thiosulfinate is rapidly degraded to related organosulfur compounds. Allicin is often thought of as the "active ingredient" in Garlic, and has been the subject of numerous scientific studies, but its a fairly unstable compound that likes to react with itself.

蒜氨酸(S-烯丙基-L-半胱氨酸亚砜，alliin)是完整、未受损大蒜里面含量最丰富的硫化物，并且非常稳定，它存在于大蒜的细胞质里；当细胞受损时，蒜氨酸酶从细胞液向细胞质释放，蒜氨酸和蒜氨酸酶接触被迅速转化为一系列新的化合物—蒜辣素及其相似物，蒜辣素(双烯丙基硫代亚磺酸酯，allicin)被认为是大蒜中最重要的活性成分，但它相当不稳定，易于自身反应。

Trifluoromethyl-3-heptadfluoroisopropyl-2-perfluoropentene-4-(N',N'-dimethylamino propyl) imino was prepared by the reaction of hexafluoropropene timer with N,N-dimethyl propanediamine in the molar ratio 1:1.0 at room temperature for 8h, and the structures of VIII were identified by IR and NMR spectra.

Benzyl isopropyl ether also forms CCT complex with oxygen on the benzene ring like phenyl isopropyl ether, but it is easy to oxidize since charge transfer and 〓 transfer may occur at the methylene group adjacent to the benzene ring, which result in the oxidation of the methylene group.(4) The 〓-CCT complex and the initial dark oxidation mechanism of poly were studied.

虽然苄基异丙醚也以苯环与O〓形成CCT复合物，但它却容易发生暗氧化，这是由于与苯基相连的是亚甲基，此时电荷转移发生在苯环与亚甲基之间，引起亚甲基的氧化，而不是异丙基的氧化。
