An efficient catalytic protocol for the three‐component assembly of benzyl bromides, carbon monoxide, and alkyl zinc reagents to give benzyl alkyl ketones is described, and represents the first nickel‐catalyzed carbonylative coupling of two sp3‐carbon fragments. The method, which relies on the application of nickelcomplexed with an NN2‐type pincer ligand and a controlled release of CO gas from a solid
The invention provides compounds of formula (I) :-
or a physiologically acceptable salt or solvate thereof wherein
R¹ represents a halogen or hydrogen atom or a C₁₋₆alkyl or C₁₋₆alkoxy group;
R² represents a phenyl group optionally substituted by one or two substituents;
R³ represents the group
R⁴ and R⁵, which may be the same or different, each independently represent a hydrogen atom or a halogen atom, or a group selected from hydroxy, C₁₋₆alkoxy or C₁₋₆alkyl.
The compounds may be used in the treatment or prophylaxis of depression and other CNS disorders.

The invention provides compounds of the Formula (I) or a pharmaceutically acceptable salts thereof, wherein X, Y, Z, R1, R2, R4, Ra, and the subscripts m, p, and q are as described herein. The compounds or their pharmaceutically acceptable salts can modulate the body's production of cyclic guanosine monophosphate ("cGMP"), and are generally suitable for the therapy and prophylaxis of diseases which are associated with a disturbed cGMP balance. The invention also provides pharmaceutical compositions which comprise compounds of Formula (I) or pharmaceutically acceptable salts thereof. The invention also relates to methods for use of the compounds or their pharmaceutically acceptable salts in the therapy and prophylaxis of the abovementioned diseases and for preparing pharmaceuticals for this purpose.
