Synthesis and group 9 complexes of macrocyclic PCP and POCOP pincer ligands
The synthesis of macrocyclic variants of commonly employed phosphine-based pincer (pro)ligands derived from meta-xylene (PCP-14) and resorcinol (POCOP-14) is described, where the P-donors are trans-substituted with a tetradecamethylene linker. The former

Process for preparing dibasic salts of bisphenols
The present invention discloses a process for preparing dibasic salt of bisphenol from bisphenol and alkali, wherein the bisphenol and the alkali are reacted in a reaction medium consisting of an organic solvent or an aqueous inorganic salt solution, and then through filtration, a highly pure dibasic salt of bisphenol is directly obtained at a yield of higher than 90%.
