Thermally stable aminosulfur trifluorides

An aminosulfur trifluoride composition having a structure with one or more:

• wherein m=1-5 and R1 and R2 are:
• (1) when m=1, individually aryl or meta- or para-substituted aryl radicals in which the meta- or para-substitution is selected from the group consisting of normal and branched C1-10, trifluoromethyl, alkoxy, aryl C6-10, nitro, sulfonic ester, N,N-dialkylamino and halogens;
• or
• (2) when m=1, individually aryl radicals which are fused or linked to one another;
• or
• (3) when m=1, one of R1 and R2 is an aryl radical and the other is an at least 5 member saturated cyclic hydrocarbon radical having zero to three heteroatoms selected from the group consisting of oxygen, nitrogen and mixtures thereof;
• or
• (4) when m=1, one of R1 and R2 is an aryl radical and the other is an at least 5 member saturated cyclic hydrocarbon radical having zero to three heteroatoms selected from the group consisting of oxygen, nitrogen and mixtures thereof wherein said cyclic hydrocarbon radical is fused to said aryl radical;
• or
• (5) when m=1, together a cyclic ring having 2 to 10 carbon ring members and an additional 1 heteroatom selected from the group consisting of oxygen, nitrogen and alkylated nitrogen wherein said ring has 1 to 2 alkoxyalkyl functionalities;
• or
• (6) when m=1, together an unsaturated cyclic ring having 2 to 4 carbon ring members and one to three additional heteroatoms selected from the group consisting of oxygen, nitrogen, protonated nitrogen and alkylated nitrogen wherein said ring has one to three functional groups selected from hydrogen, normal and branched C1-10 alkyl, haloalkyl, alkoxy, aryl halogen, cyano, nitro and amino;
• or
• (7) when m=2-5, R1 is a single phenyl radical linked to each —NSF3 radical and R2 is an aryl radical having C6 to C10;
• or
• (8) when m=2-5, R1 and R2 are individually divalent aryl radicals of C6 to C10 linked to adjacent —NSF3 radicals except R1 and R2 are monovalent aryl radicals having C6 to C10 where R1 and R2 are linked to only one —NSF3 radical.
