Three N-alkoxyamines were synthesized for use in nitroxide-mediated radical polymerization. Upon thermolysis, they generate new acyclic α-hydrogen nitroxides: one adamantyl substituted and two diol-containing nitroxides. The initiators were tested in polymerization reactions in direct comparison with the initiator derived from the nitroxide TIPNO. Georg Thieme Verlag Stuttgart.

Catalytic substitution reactions at the adamantane bridgehead were studied by using α,β- and β,γ-unsaturated trimethylsilanes.Treatment of 1-adamantyl (Ad) chloride (1) with allyltrimethylsilane and its heteroanalogues, X=Y-Z-SiMe3, in the presence of Lewis acid as a catalyst gave the products Ad-X-Y=Z, X=Y+(Ad)-Z-, and X=Y-Z-Ad, depending on the attack site of the adamantyl group on each X, Y, and Z atom.Treatment of 1 with (phenylethynyl)trimethylsilane also gave a substituted adamantane in good yield.The substitution reactions of 1 with aryl- and heteroaryltrimethylsilanes under similar conditions occurred at a position distinct from that of acetylation, indicating that adamantylation was not influenced by an electronic effect of the trimethylsilyl group.
