3-aryl- 1-alkene alkanal

This reaction has very general application in the formation of C-C bonds, including biaryls, aryl alkenes, alkanes, and even ketones. ... [Pg.2030]

This section contains dehydrogenations to form alkenes and unsaturated ketones, esters and amides. It also includes the conversion of aromatic rings to alkenes. Reduction of aryls to dienes is found in Section 377 (Alkene-Alkene). Hydrogenation of aryls to alkanes and dehydrogenations to form aryls are included in Section 74 (Alkyls from Alkenes). [Pg.219]

Often the equilibrium position of a reversible process is such that the conversion to product is low at reasonable holding times (i.e., flow rates and reactor volumes). For example, the dehydrogenation of saturated alkanes and alkyl aromatics to produce alkenes and aryl-alkenes and hydrogen is a very important case in point ... [Pg.489]

The kinetics of the oxidative addition of nitriles to Ni(P—P)2 have been studied. The organocyano nickel(II) complexes presumably have a dinuclear structure with trans planar coordination for the nickel atom.270 Some of the [Ni(CN)(R)(PR3)2] compounds (R = alkyl, aryl) are unstable and therefore cannot be isolated in the solid state. Their decomposition in solution promotes the formation of alkanes, alkenes, diphenyl, etc.217... [Pg.32]

C-Alkylations have been performed with both support-bound carbon nucleophiles and support-bound carbon electrophiles. Benzyl, allyl, and aryl halides or triflates have generally been used as the carbon electrophiles. Suitable carbon nucleophiles are boranes, organozinc and organomagnesium compounds. C-Alkylations have also been accomplished by the addition of radicals to alkenes. Polystyrene can also be alkylated under harsh conditions, e.g. by Friedel-Crafts alkylation [11-16] in the presence of strong acids. This type of reaction is incompatible with most linkers and is generally only suitable for the preparation of functionalized supports. Few examples have been reported of the preparation of alkanes by C-C bond formation on solid phase, and general methodologies for such preparations are still scarce. [Pg.171]
