In this article, a Pd-catalyzed intramol. oxidative coupling between unactivated aliphatic and aryl C-H compounds ROCH2C(CH3)2CO2H (R = C6H5, 4-ClC6H4, 2-naphthyl, etc.) has been described. This chem. showed great potential to build up fused cyclic scaffolds I (R1 = H, Me, OMe; R2 = Me, Ph, F, etc.; R3 = H, Me; R4 = H, Me; R1R2 = R3R4 = -CH=CHCH=CH-) and 3-methyl-3,4-dihydro-2H-benzofuro[2,3-h]chromene-3-carboxylic acid from linear substrates through oxidative couplings. Privileged chromane and tetralin scaffolds were constructed from readily available linear starting materials in the absence of any organohalides and organometallic partners. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Reference of 103-16-2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Reference of 103-16-2
