Addition of Lithium Reagents ofN,N-Dialkylsulfonamides to Mannich Bases
摘要:
The addition of metallated N,N-dialkyl-sulfonamides 1 to Mannich bases 2, leading to N,N-dialkylamides of 4-(N',N'-dialkylamino)-2-hydroxy-2-phenylbutanesulfonic acids (4) is described.

Some sulfur-substituted organotin compounds, R3SnCH2X, where X = SCH3, SO2C4H9-n, SO2C6H5, S+(CH3)2Z−, etc., have been synthesized and studied with regard to their solvolytic and “organometallic-like” behavior. Reactions of the organotin compounds with substrates known to be reactive toward classical organometalliccompounds tend to place these materials by comparison on the lower end of the reactivity
Disclosed are novel organotin compounds and a process for preparing same. These organotin compounds correspond to the general formula: ##EQU1## where A is alkyl of from 1 to 14 carbon atoms; aryl; substituted aryl; or R.sub.2 N-, where each R is alkyl of from 1 to 14 carbon atoms; and each R' is alkyl of from 1 to 14 carbon atoms; or aryl. The organotin compounds of the invention having insecticidal, acaricidal, bacteriostatic, fungicidal and herbicidal properties are employed in the formulation of pesticidal compositions.
