Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Tri(naphthalen-1-yl)phosphine, is researched, Molecular C30H21P, CAS is 3411-48-1, about Interface chemistry of organophosphorus compounds. II. Spreading behavior of aromatic, mixed aromatic-n-aliphatic, aromatic-cycloaliphatic, or aliphatic-cycloaliphatic phosphines.SDS of cas: 3411-48-1.
The aromatic phosphines, PRR21 (I), where R, R1 = Ph, α- or β-naphthyl, p-biphenylyl, or anthryl), or their oxides do not form monolayers at the air/H2O interface, due to the electron withdrawing character of the aromatic rings, which makes the free electron pair of P unavailable for solvation. The introduction of Me as an electron repelling group, as in tri-p-tolylphosphine, leads to the formation of multimol. films. The mol. area of the nonspreading I (R = R1 = Ph) (Ia) was determined from the increase in area caused by the addition of Ia to the spreading I (R = R1 = n-C8H17). The mol. of Ia is pyramidal in the mixed films. The spreading properties of mixed I, where R, R1 = aliphatic or aromatic., are a combination of the properties of the individual I, where R = R1 = aliphatic or aromatic. I (R = R1 = cyclohexyl) (Ib) forms real gas-analogous films. The observed mol. area is smaller than the calculated area, due to the bulky structure of the cyclohexyl groups. Replacement of 1-2 cyclohexyl groups with aliphatic or aromatic groups results in improvement or deterioration resp. of the spreading properties of the phosphines.
From this literature《Interface chemistry of organophosphorus compounds. II. Spreading behavior of aromatic, mixed aromatic-n-aliphatic, aromatic-cycloaliphatic, or aliphatic-cycloaliphatic phosphines》,we know some information about this compound(3411-48-1)SDS of cas: 3411-48-1, but this is not all information, there are many literatures related to this compound(3411-48-1).
