Cationic Palladium

The development of a new, highly efficient, and simple method for masking carbonyl groups as acetals and ketals is described. This methodology relies on the nature of the palladium catalyst to direct the acetalization/ketalization reaction. This new protocol is mild and proceed with a very low catalyst loading at ambient temperatures. The method has been extended to a wide variety of different carbonyl compounds with various steric encumbrances to form the corresponding acetals and ketals in excellent yields.

 C22-CuI complex , has been reported as a highly-active, efficient catalyst based on copper(I),for the synthesis of diorganyl- monochalcogenides. In addition to thermal- and air-stability, facile preparation of this homogeneous copper(I) catalyst, the corresponding products obtained in good to excellent yields and with the short reaction times. Remarkably, it was observed that diaryl/dialkyl dichalcogenides could be successfully cross-coupled with electronically and sterically diverse arylboronic acids.
