out in neat substrates without additional solvents. The ionic character of dimcarb enables the immobilization of the active catalysts in the reactive ionicliquid, using sulfonated ligands. Investigations regarding the hydroamination of 1,3-dienes led to a total turnover number (TTON) of more than 8,700 with β-farnesene in 12 repetitive recycling experiments. The telomerization of 1,3-butadiene was carried

The present application provides a terpene analogue of Formula (I) or a pharmaceutically acceptable isomer, salt or ester thereof, and methods and uses thereof for treating neurological conditions such as pain in general and neuropathic pain. These terpene analogues can also be used to treat other electrical disorders in the central and peripheral nervous system. Also provided are methods of synthesizing the terpene analogues of Formula I.
Polymers of structure (I):
in which, R¹ is a saturated or unsaturated C₆ to C₂₀ alkyl group; R² and R³ are the same or different and are each C₁₋₄alkyl; X⁻ is a physiologically acceptable counter ion; a, b and c are numbers which indicate the relative molar percentages of the units present in a random distribution in said polymer, (b) being from about 0.5 to about 10 molar percent, and (c) being from about 30 to about 99 molar percent; and n is a number indicating the number of repeating units in said polymer, processes for their preparation, intermediates useful in their preparation, pharmaceutical compositions containing them and their use in therapy for the lowering of serum cholesterol levels in humans.
