Novel phosphites have the formula I
P(O—R1)x(O—R2)y(O—R3)z(O—R4)p I
where
R1: aromatic radical having a C1-C18-alkyl substituent in the o position relative to the oxygen atom which connects the phosphorus atom to the aromatic system, or having an aromatic substituent in the o position relative to the oxygen atom which connects the phosphorus atom to the aromatic system, or having an aromatic system fused on in the o position relative to the oxygen atom which connects the phosphorus atom to the aromatic system,
R2: aromatic radical having a C1-C18-alkyl substituent in the m position relative to the oxygen atom which connects the phosphorus atom to the aromatic system, or having an aromatic substituent in the m position relative to the oxygen atom which connects the phosphorus atom to the aromatic system, or having an aromatic system fused on in the m position relative to the oxygen atom which connects the phosphorus atom to the aromatic system, where the aromatic radical bears a hydrogen atom in the o position relative to the oxygen atom which connects the phosphorus atom to the aromatic system,
R3: aromatic radical having a C1-C18-alkyl substituent in the p position relative to the oxygen atom which connects the phosphorus atom to the aromatic system, or having an aromatic substituent in the p position relative to the oxygen atom which connects the phosphorus atom to the aromatic system, where the aromatic radical bears a hydrogen atom in the o position relative to the oxygen atom which connects the phosphorus atom to the aromatic system,
R4: aromatic radical which bears substituents other than those defined for R1, R2 and R3 in the o, m and p positions relative to the oxygen atom which connects the phosphorus atom to the aromatic system, where the aromatic radical bears a hydrogen atom in the o position relative to the oxygen atom which connects the phosphorus atom to the aromatic system,
x: 1 or 2,
y, z, p: independently of one another, 0, 1 or 2, with the proviso that x+y+z+p=3.
新型磷酸酯的化学式为IP(O—R1)x(O—R2)y(O—R3)z(O—R4)p,其中R1:芳香基团,在连接磷原子和芳香系统的氧原子的o位具有C1-C18烷基取代基,或在连接磷原子和芳香系统的氧原子的o位具有芳香基取代基,或在连接磷原子和芳香系统的氧原子的o位具有融合芳香系统;R2:芳香基团,在连接磷原子和芳香系统的氧原子的m位具有C1-C18烷基取代基,或在连接磷原子和芳香系统的氧原子的m位具有芳香基取代基,或在连接磷原子和芳香系统的氧原子的m位具有融合芳香系统,在连接磷原子和芳香系统的氧原子的o位具有氢原子;R3:芳香基团,在连接磷原子和芳香系统的氧原子的p位具有C1-C18烷基取代基,或在连接磷原子和芳香系统的氧原子的p位具有芳香基取代基,在连接磷原子和芳香系统的氧原子的o位具有氢原子;R4:芳香基团,在连接磷原子和芳香系统的氧原子的o、m、p位除了R1、R2和R3定义的取代基外,还带有其他取代基,在连接磷原子和芳香系统的氧原子的o位具有氢原子;x:1或2;y、z、p:相互独立,为0、1或2,但必须满足x+y+z+p=3。
