Abstract
Disclosed is a compound of the formula wherein Ra and Rb each, independently of the other, are hydrogen, alkyl, aryl, arylalkyl, or alkylaryl, R1 and R2 each, independently of the other, are hydrogen, alkyl, aryl, arylalkyl, or alkylaryl, provided that at least one of R1 and R2 is other than hydrogen, and R3, R4, R5, R6, and R7 each, independently of the others, are alkyl, aryl, arylalkyl, alkylaryl, or a substituent other than hydrogen, alkyl, aryl, arylalkyl, or alkylaryl, wherein in each case alkyl, aryl, arylalkyl, or alkylaryl may or may not be substituted and may or may not have hetero atoms therein, and wherein two or more of R3, R4, R5, R6, and R7 can be joined together to form a ring.
