Title cpds. are of formula (I): where R = 1-2 C alkyl; R1 = 3-5 C alkyl, 3-5C alkenyl, 3-5 C alkynyl, or phenyl-(1-4 C alkyl); R2 = S-(1-4C alkyl), SCH2S(1-4 C alkyl), -SO(1-4 C alkyl), -CH2SO(1-4 C alkyl), -SO2(1-4 C alkyl), -CH2SO2(1-4 C alkyl), S-(CH2)nCN, -S(CH2)mCl, -SCCl3, -S(CH2)mCO2R3, -S(CH2)mCONR4R5, -SO(CH2)mCN, -SO(CH2)mCl, -SO(CH2)mCO2R3, -SO(CH2)mCONR4R5, -SO2(CH2)mCN, -SO2(CH2)mCl, -SO2(CH2)mCO2R3, or -SO2(CH2)mCONR4R5; R3 = alkyl; R4 and R5 = H or alkyl; m = 1 or 2; n = 0-2; and X = hal or 1-4 C alkyl; (I) are prepd. e.g. by condensing (RO)(R1S)P(=O)Cl with a phenol and base or a metal salt of the phenol. |
