Palladium- vs. peroxide-promoted decarbonylation of neophyl-like aldehydes

A general and efficient aldehyde decarbonylation reaction by using a palladium catalyst

“…10,11 Hence, an effective and versatile synthetic decarbonylation process can be beneficial for the generation of fuel grade alkanes and should be an attractive alternative to existing expensive hydrogenation methodologies. 10 Various metal-based systems have been investigated successfully for decarbonylation reactions including those with Ru, 12 Ir, 13 Rh [14][15][16][17][18][19] and Pd [20][21][22][23][24][25][26] at 180-280 1C with limited substrate scope. However, very few of the existing decarbonylation catalysts are easily available and almost all of them are costly.…”

Electrochemical Energy Conversion: Past, Present, and Future

“…C(O)R radical intermediate A in the presence of DTBP under heating conditions, followed by loss of CO to give alkyl radical intermediate (R . ) B 6a,7c,8b,d,e,h. Addition of alkyl radical intermediate B to the carbon‐carbon triple bond of alkyne 1 takes place to form vinyl radical intermediate C .…”

Selective Decarbonylation via Transition-Metal-Catalyzed Carbon–Carbon Bond Cleavage

“…In 1965, Tsuji and Ohno reported the first example of the Pd-catalyzed decarbonylation of aldehydes with Pd/C or PdCl 2 as the catalyst . Since then, the decarbonylation of aldehydes has been accomplished by catalysts containing Rh, Ni, Rh, − Ir, − Ru, , and Pd. − This reaction allows for an aldehyde group to be used as a removable functional group and has consequently been widely used in organic syntheses. For example, Carreira et al developed a strategy to form 1,1-diarylethane compounds in high yield and optical purity (Scheme B) .…”
