The addition of various Grignardreagents to P-t-butyl-P-phenyl-N-phosphinoyl benzaldimine provides a stereoselective method for the synthesis of chiral phosphinoylamines.

Nitroxyl‐Radical‐Catalyzed Oxidative Coupling of Amides with Silylated Nucleophiles through N‐Halogenation
(EWG) and silylatednucleophiles was developed to furnish coupling products in high yields, thus opening up new frontiers in organocatalyzed reactions. This reaction proceeded through the activation of N‐halogenated amides by a nitroxyl‐radical catalyst, followed by carbon–carbon coupling with silylatednucleophiles. Studies of the reaction mechanism indicated that the nitroxyl radical activates N‐halogenated
Stereoselective Addition of Grignard Reagents to New P-Chirogenic N-Phosphinoylbenzaldimines: Effect of the Phosphorus Substituents on the Stereoselectivity
give both diastereoisomers in high yields and with promising diastereomeric ratios. Then N-[(tert-butyl)(phenyl)phosphinoyl]benzaldimine, which displayed the best results, was subjected to the 1,2-addition of various Grignardreagents to evaluate the best chiral induction due to the stereogenic phosphorus atom. The corresponding adducts were obtained in excellent yields and with moderate to excellent diastereoisomeric
