| abstract | 1,234,918. Dialkyl and diphenyl tin bis (maleic acid monoesters). TENNECO CHEMICALS Inc. 5 Feb., 1970 [5 Feb., 1969], No. 5650/70. Heading C2J. [Also in Division C3] Organotin stabilizers for vinyl resins (see Division C3) have the formula where R is phenyl or a C 4 -C 8 alkyl group, R<SP>1</SP> is H or a C 1 -C 4 alkyl group, and R<SP>2</SP> is methyl or phenyl. Specified compounds are (i) di-nbutyltin bis (monobutenyl maleate), R<SP>1</SP>=H, R<SP>2</SP>=CH 3 ; (ii) di-n-butyltin bis (monocinnamyl maleate), R<SP>1</SP>=H, R<SP>2</SP>=C 6 H 5 ; (iii) di-n-butyltin bis (mono-4-hexen-3-yl maleate), R<SP>1</SP>=C 2 H 5 , R<SP>2</SP> =CH 3 ; (iv) di-n-hexyltin bis (mono-2-octen-4- yl maleate), R<SP>1</SP>=C 4 H 9 , R<SP>2</SP>=CH 3 ; and (v) di-2- ethylhexyltin bis (mono-3-penten-2-yl maleate), R<SP>1</SP>=CH 3 , R<SP>2</SP>=CH 3 . The compounds may be prepared by reacting R 2 SnO with the appropriate maleic acid monoester in a solvent. Examples describe the preparation of compounds (i) and (ii). |
