Trityl Chloride: As a multi propose reagent

Zaira Dominguez et.al, using coupling reaction, described an efficient and convenient method for the synthesis of 1,4-bis(3,3,3-triphenylpropynyl)-benzene by the reaction of 3,3,3-triphenylpropyne, produced by the reaction of trityl chloride and prop-1-yn-1-yl magnesium bromide, with 1,4 diiodo benzene in the presence of catalyst (Pd(0)-catalyzed). Pd(0) has been applied for coupling reaction of 2.5 equiv of alkyne 1 with 1,4-diiodobenzene in refluxing in piperidine to yield rotors and so on
