  • S-tert-Butyl-L-cysteine hydrochloride to S-tert-butyl-L-cysteine tert-butyl ester hydrochloride.[2]
  • Lanthanide isopropoxides to lanthanide tert-butoxides in cyclohexane.[3]

Three hyperbranched fluoropolymers were synthesized and their micelles were constructed as potential (19)F MRI agents. A hyperbranched star-like core was first synthesized via atom transfer radical self-condensing vinyl (co)polymerization (ATR-SCVCP) of 4-chloromethyl styrene (CMS), lauryl acrylate (LA), and 1,1,1-tris(4'-(2''-bromoisobutyryloxy)phenyl)ethane (TBBPE).
