New heterotelechelic PEG-containing benzaldehyde and 2-pyridyldithio endgroup (CHO-Bz-PEG-SSpyl) was synthesized with high efficiency and high selectivity. An alpha-benzylacetal-omega-methansulfonyl PEG was prepared as the first step to CHO-Bz-PEG-SSpyl through the ring-opening polymerization of ethylene oxide (EO) initiated by potassium 4-(diethoxymethyl)benzyl alkoxide
