α-ISOCYANATO AND α-ISOTHIOCYANATO AZOS AND THEIR DERIVATIVES

Claim 1

A compound of the formula ##STR77## where: a. n is 1 or 2; b. R', R" and R'" are selected from alkyl of 1-8 carbons and and aralkyl of 7-12 carbons, or 2 or more of R', R" and R'" joined with the tertiary carbon atom to which they are attached form cycloalkyl of 3-12 carbons: or R" is aryl of 6-14 carbons; or R'" is cyano or Y; c. R 1 and R 2 are selected from alkyl of 1-8 carbons, cycloalkyl of 3-12 carbons, aralkyl of 7-12 carbons, or taken together are alkylene of 3-11 carbons; or R 2 is aryl of 6-14 carbons; d. Z, when n is 1, and Y have the same definition and are selected from: ##STR78## e. X is oxygen or sulfur; f. R 3 and R 4 are selected from hydrogen, alkyl of 1-12 carbons, cycloalkyl or 3-12 carbons, aralkyl of 7-12 carbons, aryl of 6-14 carbons and, taken together, alkylene of 3-11 carbons; g. R 5 is selected from alkyl of 1-12 carbons, cycloalkyl of 3-12 carbons, aralkyl of 7-12 carbons and aryl of 6-14 carbons; h. R 6 is selected from hydrogen, alkyl of 1-8 carbons, cycloalkyl of 3-8 carbons, aralkyl of 7-12 carbons and aryl of 6-14 carbons; i. R 7 is selected from primary or secondary alkyl of 1-12 carbons and cycloalkyl of 3-12 carbons; j. R 8 is selected from tertiary alkyl of 4-8 carbons and aryl of 6-14 carbons; and k. R 9 is a hydrocarbyl diradical selected from aliphatic hydrocarbyl of 2-20 carbons, cycloaliphatic hydrocarbyl of 3-20 carbons, aliphatic-cycloaliphatic hydrocarbyl of 4-20 carbons and aromaticaliphatic hydrocarbyl of 7-20 carbons optionally containing one or more nonadjacent and nonterminal oxygen, sulfur or nitrogen atoms in the backbone structure, and from aromatic of 6-12 carbons.
