[Problem] To exhibit an insect-repelling effect while suppressing insect repellent intake by people, etc., and to prolong said insect-repelling effect.

[Solution] This inject repellent fiber (1), which can release an insect repellent, comprises a core part (2) which contains an insect repellent (4) and which is formed from a thermoplastic resin, and a sheath part (3) which contacts the outer surface of the core part to cover the core part and which is formed from a thermoplastic resin. The crystallinity of the thermoplastic resin configuring the sheath part is less than or equal to the crystallinity of the thermoplastic resin configuring the core part.

A composition that includes one or more compounds represented by the formula
R.sub.1OR.sub.2
wherein R.sub.1 is a substituted or unsubstituted aryl or polyaryl group having from about 4 to about 40 carbon atoms, and R.sub.2 is a substituted or unsubstituted, linear or branched, alkyl group having from about 4 to about 40 carbon atoms. The composition has a viscosity (Kv.sub.100) from about 1 to about 10 cSt at 100 C. as determined by ASTM D-445, a viscosity index (VI) from about 100 to about 300 as determined by ASTM D-2270, and a Noack volatility of no greater than 50 percent as determined by ASTM D-5800. The disclosure also relates to a process for producing the composition, a lubricating oil base stock and lubricating oil containing the composition, and a method of reducing boundary friction and improving dispersancy of polar additives of a lubricating oil by using as the lubricating oil a formulated oil containing the composition.

Disclosed are methods for rerouting radical cascade cyclizations by using alkenes as alkyne equivalents. The reaction sequence is initiated by a novel 1,2 stannyl shift which achieves chemo- and regioselectivity in the process. The radical hopping leads to the formation of the radical center necessary for the sequence of selective cyclizations and fragmentations to follow. In the last step of the cascade, the elimination of a rationally designed radical leaving group via -CC bond scission aromatizes the product without the need for external oxidant. The Bu.sub.3Sn moiety, which is installed during the reaction sequence, allows further functionalization of the product via facile reactions with electrophiles as well as Stille and Suzuki cross-coupling reactions. This selective radical transformation opens a new approach for the controlled transformation of enynes into extended polycyclic structures of tunable dimensions.
