| 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.
