Abstract

Optimum conditions for the synthesis of aryl‐dibenzo‐oxaphosphorines (2) from the corresponding phosphonous chloride (1) were explored to avoid the formation of by‐products (e.g., 4–6). The aryl‐dibenzo‐oxaphosphorines (2) were converted to the P‐oxides (3), and were utilized in the synthesis of phosphinite‐boranes 7 and Pt(II) complexes 8. Depending on the aryl substituent, the Pt(II) complex (8) was formed with cis and trans geometry. © 2004 Wiley Periodicals, Inc.
