An efficient radical addition/elimination reaction that enables selective incorporation of alkenyl, alkynyl and allyl functional groups into the C(sp3)-H bond under green reaction conditions is developed. The process is based on the catalytic formation of α-alkoxyl/α-amidyl radicals via the homolytic activation of the C(sp3)-H bond of ethers/amides with a catalytic amount of diarylketone in the presence of a household fluorescent light bulb. This simple reaction protocol features good functional group tolerance, scalability, convenient reagents and operating systems. Synthetic application of the method has been demonstrated via the preparation of natural products and different valuable synthones.
Regio- and stereoselective Au(I)-catalyzed intermolecular hydroalkoxylation of aryl allenes

In the presence of a catalytic amount of Ph3PAuNO3 and H2SO4, the hydroalkoxylation of allenes with alcohols has been shown to proceed smoothly and give allylic ethers in good yields and high regio- and stereoselectivity. Georg Thieme Verlag Stuttgart.

The palladium-catalyzed coupling of alkynes with alcohols and carboxylic acids to give allylic ethers and esters has been achieved. With phenols, these conditions furnish the C-alkylation products.
