Abstract: PURPOSE:To obtain a new phosphite containing a monovinyl aromatic group and at least one S-P bond, and useful for raw material of resin for optical material such as lens having high refractive index, coating, ink, adhesive, etc. CONSTITUTION:A compound expressed by formula I[A1 is (X1-R3)m (X1 is O or S; R3 is alkylene, phenylene, toluene-alpha-diyl, etc.; (m) is integer of >=0) or group expressed by the formula R4-(X1-R3)m (R4 is same as R3); Y1 and Y2 are H, halogen, alkyl, alkoxy or alkylthio; M is H or alkali metal] is made to react with a phosphorus halide compound expressed by formula II (R1 and R2 are alkyl, aryl, alkoxy, alkylthio, etc.; Z is halogen; (k) and (e) are 0 or 1) to provide the objective phosphite compound expressed by formula III. Furthermore, polymerization of the compound using a radical polymerization initiator gives a polymer for optical material, etc., having small specific gravity and good transparency and weather resistance.

Abstract: NEW MATERIAL:An O-ethyl-S-n-propyl S-substituted carbamoylmethyl phosphate derivative of formula III (R is alkyl or benzyl group; X is halogen; n is 0, 1, or 2). EXAMPLE:O-Ethyl S-n-propyl S-(N-dibenzylcarbamoylmethyl) phosphorodithioate. USE:Insecticides and miticides capable of controlling a wide variety of harmful insects, mites, particularly tobacco cutworm and diamondback moth, without doin damage to crops. PROCESS:A compound of formula I (M is alkali metal or quaternary ammonium) is reacted with a compound of formula II (Hal is halogen) in an organic solvent, e.g a ketone or nitrile, at room temperature to 100 deg.C, preferably 30-80 deg.C, to give the compound of formula III.

Abstract: Improved methods for converting phosphite or phosphonate esters into corresponding thiophosphites or thiophosphonates and for synthesizing specific thiophosphite and thiophosphonate compounds so produced are disclosed and claimed. The methods start from phosphite diesters using P4S10 as the thionation reagent. The reaction mixture is refluxed until the reaction is complete and may be followed by separation and chloroformate ester phosphonation steps to produce pure thiophosphonocarboxylate triesters. Alternatively, these esters may be prepared directly by action of P4S10 on the corresponding phosphonocarboxylate esters. The former method was used to prepare dimethyl thiophosphite and thence trimethyl thiophosphonoformate, a key intermediate in synthesis of salts of thiophosphonoformic acid, which have anti-viral properties.
Abstract translation: 将亚磷酸酯或膦酸酯转化成相应的硫代亚磷酸酯或硫代膦酸酯并合成如此生产的特定硫代亚磷酸酯和硫代膦酸酯化合物的改进方法被公开和要求保护。 方法从使用P4S10作为硫化试剂的亚磷酸二酯开始。 将反应混合物回流直到反应完成，然后分离和氯甲酸酯膦酸化步骤以产生纯的硫代膦酰基羧酸酯三酯。 或者，这些酯可以直接通过P4S10在相应的膦酰基羧酸酯上的作用来制备。 使用前一种方法制备二硫代亚磷酸二甲酯，然后制备硫代膦酰甲酸三甲酯，这是合成硫代膦酰甲酸盐的关键中间体，具有抗病毒性质。
