Precatalysts and process for the metal-free functionalization of SP2 carbons using the same

Precatalysts and catalytic processes for the functionalization of sp.sup.2-carbons using the precatalysts are described herein. The precatalysts comprise an intramolecular Frustrated Lewis Pair (FLP) that is generated in situ from the corresponding precatalyst fluoroborate salts. The precatalyst fluoroborate salts are deprotected in situ to generate catalysts including intramolecular FLPs for the dehydrogenative borylation of alkenes, arenes and heteroarenes. The catalytic process comprises contacting a precatalyst, a functionalization reagent; and a substrate comprising a sp.sup.2-H carbon, under conditions to provide a substrate comprising a functionalized sp.sup.2 carbon.

CHALCOGENIDE HYBRID INORGANIC/ORGANIC POLYMER (CHIP) MATERIALS AS IMPROVED CROSSLINKING AGENTS FOR VULCANIZATION

Methods of vulcanization using a high content sulfur polymer, instead of elemental sulfur, have been developed. These high sulfur content polymers are referred to as Chalcogenide Hybrid Inorganic/Organic Polymers (CHIP) materials and have good polymer compatibility in that they are soluble in a number of polymers. Furthermore, CHIP materials may have weaker bonds than the SS bonds of elemental sulfur and thus provide for a higher crosslinking efficiency vulcanization.
