Patent ID: 8110695

Claim:
A compound selected from the group consisting of Formula III, Formula IV, Formula I, Formula II, Formula VI, and Formula VII: wherein A is a member selected from the group consisting of silicon and boron; X and X′ are independently aliphatic or aromatic groups which are each independently selected from the group consisting of alkyl, alkenyl, alkynyl, aryl, heteroaryl, heterocyclyl, wherein the alkyl, alkenyl, and alkynyl, groups may be substituted by one or more heteroatoms, and when one or more heteroatoms is present in the alkyl, alkenyl, and alkynyl groups and in the heteroaryl and heterocyclyl groups, the heteroatoms are selected from the group consisting of nitrogen, phosphorous, arsenic, antimony, bismuth, germanium, tin, oxygen, sulfur, selenium, tellurium, boron, aluminum, gallium, indium, germanium, and silicon, and wherein all of the alkyl, alkenyl, alkynyl, aryl, heteroaryl, heterocyclyl groups also may be optionally substituted by one or more of the following: alkyl, alkenyl, alkynyl, aryl, heteroaryl, heterocyclyl, halo, cyano, oxo, hydroxy, mercapto, sulfonyl, sulfoxy, amino, imino, alkylthio, alkoxy, alkoxyalkyl, mono-alkylamino, di-alkylamino, nitro, nitroso, and thioxo; R 1 , R 2 , R 3 , and R 4 are each independently selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, aryl, heteroaryl, heterocyclyl, halo, cyano, hydroxy, mercapto, sulfonyl, sulfoxy, amino, alkylthio, alkoxy, alkoxyalkyl, mono-alkylamino, di-alkylamino, nitro, and nitroso, or R 1 and R 2 together with the atoms connected to them or R 3 and R 4 together with the atoms connected to them may form a spiro C 4-8 cycloalkyl group that may optionally contain one or more heteroatoms selected from the group consisting of nitrogen, phosphorous, arsenic, antimony, bismuth, germanium, tin, oxygen, sulfur, selenium, tellurium, boron, aluminum, gallium, indium, germanium, and silicon; or R 1 and R 3 together with the atoms connected to them or R 2 and R 4 together with the atoms connected to them may form a C 3-10 cycloalkyl group that may optionally contain one or more heteroatoms selected from the group consisting of nitrogen, phosphorous, arsenic, antimony, bismuth, germanium, tin, oxygen, sulfur, selenium, tellurium, boron, aluminum, gallium, indium, germanium, and silicon; and wherein Y is a counterion.
