Synthesis of diphenylhexatriene by the Pd-catalyzed dimerization of cinnamyl acetate
Mesganaw, Tehetena,Im, G-Yoon J.,Garg, Neil K.
, p. 3391 - 3393 (2013)
A mild and operationally simple method to synthesize diphenylhexatriene (DPH) is reported. The method relies on the Pd-catalyzed dimerization of cinnamyl acetate and provides efficient access to DPH in a single step.
Palladium-Catalyzed Three-Component Reaction of 3-(Tri-n- butylstannyl)allyl Acetates, Aldehydes, and Triorganoboranes: An Alternative to the Carbonyl Allylation Using α,γ-Substituted Allylic Tin Reagents

A three-component reaction of 3-(tri-n-butylstannyl)allyl acetates, aldehydes, and triorganoboranes in the presence of a palladium-Xantphos catalyst system predominately gave (E)-anti-homoallylic alcohols with high diastereoselectivity and good to high levels of alkene stereocontrol. An efficient chirality transfer was observed when an enantioenriched substrate was employed. The reaction was initiated by the formation of an allylic gem-palladium/stannyl intermediate, which subsequently underwent allylation of the aldehyde by an allyltributyltin followed by a coupling reaction of the in-situ-generated (E)-vinylpalladium acetate with the triorganoborane.
Z-selective metathesis homocoupling of 1,3-dienes by molybdenum and tungsten monoaryloxide pyrrolide (MAP) complexes

Molybdenum or tungsten monoaryloxide pyrrolide (MAP) complexes that contain OHIPT as the aryloxide (hexaisopropylterphenoxide) are effective catalysts for homocoupling of simple (E)-1,3-dienes to give (E,Z,E)-trienes in high yield and with high Z selectivities. A vinylalkylidene MAP species was shown to have the expected syn structure in an X-ray study. MAP catalysts that contain OHMT (hexamethylterphenoxide) are relatively inefficient.
