Synthesis of two p-methoxyphenyl substituted phosphines

GRAPHICAL ABSTRACT

ABSTRACT

Bis(m-methoxyphenyl)(p-methoxyphenyl)phosphine (1) and di(n-butyl)(p-methoxy-phenyl)-phosphine (4) were synthesized and characterized by ¹H, ¹³C, and ³¹P NMR spectroscopy and 1 also by single crystal X-ray diffraction. The syntheses and analytical data are discussed.
