Direct use of allylic alcohols and allylic amines in palladium-catalyzed allylic amination
Chemical Communications, 2017Allylic alcohols and allylic amines were directly utilized in a Pd-catalyzed hydrogen-bond-activated allylic amination under mild reaction conditions in the absence of any additives. The catalytic system is compatible with a variety of functional groups and can be used to prepare a wide range of linear allylic amines in good to excellent yields.

Allylation of quinones by allylic indium reagents
Journal of Organometallic Chemistry, 1991Abstract Allylation of a variety of quinones by allylic indium sesquihalides was studied. Reactions of unsubstituted p -benzoquinone with allylindium, prenylindium, and geranylindium reagents gave, after oxidation with silver oxide, the corresponding allylated quinones in good yields. These reactions appear to proceed via 1,2-addition of the allylic

Cycloadditions of allyl cations, 22. Allyl alcohols as precursors of allyl cations
Chemische Berichte, 1980AbstractAllyl alcohols such as 3‐ethoxy‐2‐methyl‐3‐buten‐2‐ol (4), the silylated alcohol 8 and also 2‐methyl‐3‐pentyn‐2‐ol (12) have been converted into the corresponding trifluoroacetates (5, 9, 13), which in the presence of zinc halide/ethyldiisopropylamine react with conjugated dienes to form bridged seven‐membered rings (14, 16, 18, 20–24) in good ...

Direct conversion of allylic nitro compounds into allyl sulphides and allyl sulphones
Journal of the Chemical Society, Chemical Communications, 1985Allylic nitro compounds are directly converted into allyl sulphides or allyl sulphones with high regioselectivity on treatment with sodium benzenethiolate alone or with sodium benzenesulphinate in the presence of a catalytic amount of Pd(PPh3)4.

Solvent-Mediated Allylation of Carbonyl Compounds with Allylic Stannanes
The Journal of Organic Chemistry, 1997Methanol promotes the addition of allyltrimethylstannane (1a) to isobutyraldehyde (2a, 30 degrees C) yielding the corresponding homoallylic alcohol (3a), without the necessity for added catalyst. The corresponding reaction of aldehydes 2a-eor activated ketone 2f with tetraallyltin (1b, 0.25 equiv) is substantially faster and proceeds in high yield (81 ...

Rearrangement of allylic sulfoximines to allylic sulfinamides
Tetrahedron Letters, 1994Abstract Thermolysis of the enantiomerically pure allylic sulfoximines 3a,b leads to their partial rearrangement to the isomeric allylic sulfinamides 5a,b and 6a,b, respectively, with complete retention of configuration at the S-atom. Racemization of the allylic sulfoximines 3a,b at the S-atom does not occur.
