Claims5
An azaphospholene of the formula ##STR8## wherein R.sub.1 and R.sub.2 each independently is lower alkyl, aryl or aralkyl.
Bis-(3R)-3-{(1R,5R,8 R)-5,9,9-trimethyl-4-[(1R)-1-phenylethyl]-4-aza-5-phosphatricyclo-[6.1.1.s up.1.8.0.sup.2.6 ]-dec-2(6)-enyl}.
A process for preparing bis-(3R)-3-((1R,5R,8R)-5,9,9-trimethyl-4-[(1R)-1-phenylethyl]-4-aza-5-phos phatricyclo-[6.1.1.sup.1.8.0.sup.2.6 ]-dec-2(6)-enyl), comprising reacting phenylethylamine and myrtenal at about 70.degree. to 80.degree. C. to obtain (1R,5S)-6,6-dimethyl-2-[(1R)-1-N-phenylethyl-azamethino]bicyclo[3.1.1]hept -2-ene, reacting that compound in a second step with methyldibromophosphane to form 5-bromo-5-5,9,9-trimethyl-4-[(1R)-1-phenylethyl]-4-aza-5-.lambda..sup.4 -phosphoniatricyclo-[6.1.1.sup.1.8.0.sup.2.6 ]-dec-2(6)-ene bromide, and treating such product in the cold with excess active magnesium.
