The present invention provides a catalyst complex or ligand, and compositions thereof, for use in a variety of organic reactions having high reactivity and enantioselectivity. The catalyst is a N-heterocyclic carbene having three fused rings with first and second rings being six-membered rings and the third being a five-membered ring. The first ring is fused to the second and has four substituents. The second ring has two nitrogens flanking a carbene atom with one nitrogen bound to a substituent. The carbene atom may optionally be bonded to a metal. The third ring is fused to the second ring and contains two nitrogens. The third ring of the catalyst has a double bond and two substituents on adjacent non-fused carbons. A non-fused nitrogen of the third ring is partially bonded to another substituent. Methods for the synthesis and use of the catalyst embodiments of the present invention are also provided.

[object Object]

A tricolor signal flare projectile configured for use with a 'high-low' projectile launching system such as the U.S. Army's M-433. The projectile includes a body having a cylindrical side wall and an aft closure. The body's forward portion is open, which provides access to a hollow interior. A delay assembly is installed in the aft closure. The delay assembly includes a delay column. A signal igniter is located just forward of the delay column in the hollow interior of the body. The hollow interior also includes separate volumes of red, white, and blue illuminant. An ogive closes over the top of the hollow interior of the body, thereby encapsulating the other components. When the projectile is fired from a launcher the propellant gases burning with the launcher ignite the delay column. The delay column burns while the projectile travels along its trajectory. After the passage of a desired time interval, the delay column ignites the signal igniter. The signal igniter (1) commences the ignition of the three separate volumes of illuminant; and (2) blows the three separate volumes of illuminant clear of the body.
