Compounds with the 1,3,5,2‐Triazaphosphorinane Skeleton: Synthesis and Coordination Chemistry of Novel N,N,N′‐Trimethylethylenediamine‐Substituted Compounds with Three‐and Four‐Coordinate Phosphorus
Substitution of chlorine for the N,N,N′‐trimethylethylenediamine group in the 1,3,5‐trimethylbiuret derivative 2 produced 4. The reaction of the 1,3,5,2‐triazaphosphorinane 4 with sulfur furnished the expected P(=S) derivative 5. Reaction of 4 with methyl iodide led to the formation of the ammonium iodide 6 by methylation of the nitrogen atom of the terminal NMe~2~ group while the phosphorus atom of 4 remained unaffected. The structure of 6 was confirmed by a single‐crystal X‐ray structure analysis. In the unusual reaction of 4 with Br~2~ the bromodimethylammonium‐bromophosphonium dibromide 7 was formed. The reaction of 4 with Fe~2~(CO)~9~ furnished the expected Fe(CO)~4~ complex 8 while with (C~7~H~8~)Cr(CO)~4~ (C~7~H~8~norbornadiene) 9 was obtained. In 9, norbornadiene is replaced by one molecule of 4, which is coordinated by phosphorus and the nitrogen atom of the NMe~2~ group. In the reaction of 4 with C~7~H~8~Mo(CO)~4~ (C~7~H~8~norbornadiene) the complexes 10a and 10b were formed. In 10a, the P(III) atom of 4 is coordinated to Mo; the second coordination site at Mo(CO)~4~ is occupied by the nitrogen atom of the terminal NMe~2~ group. In 10b, the nitrogen atoms of the PN(Me) and of the NMe~2~ grouping are coordinated to Mo, with formation of a five‐membered ring.
