Nitrosyltris (triphenylphosphine) rhodium is a complex compound of rhodium with the composition Rh [P (C ₆ H ₅ ) ₃ ] ₃ (NO), red crystals.

Content

Getting

To an alcoholic solution of rhodium (III) chloride are added solutions of N-methyl-N-nitrosop-toluenesulfamide and triphenylphosphine in an inert atmosphere:

{\mathsf {RhCl_{3}+3P(C_{6}H_{5})_{3}\ {\xrightarrow {CH_{3}(NO)SO_{2}C_{6}H_{4}CH_{3}}}\ Rh[P(C_{6}H_{5})_{3}]_{3}(NO)}}

{\ displaystyle {\ mathsf {RhCl_ {3} + 3P (C_ {6} H_ {5}) _ {3} \ {\ xrightarrow {CH_ {3} (NO) SO_ {2} C_ {6} H_ {4 } CH_ {3}}} \ Rh [P (C_ {6} H_ {5}) _ {3}] _ {3} (NO)}}}

Passing nitric monoxide through a solution of rhodium (III) chloride in tetrahydrofuran in the presence of an excess of triphenylphosphine .
