“…Oligomers 2 and 4 were prepared from the commercially available oligomer 1 (both PIB 1000 and PIB 2300 were used) following reported procedures . The thiol‐terminated oligomer 3 was prepared by reaction of thiourea with a bromo‐terminated PIB oligomer in a heptane/acetone mixture . Hydrolysis in an ethanol‐heptane mixture afforded 3 as a viscous oil with a CH 2 SH terminal group that appeared as a double of doublets in 1 H NMR spectroscopy centered at 2.49 δ.…”
