Procedure: Using the same conditions as in Example 4, 17 parts of 2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one and 9 parts of allyl isocyanate afforded 26 parts of 4-allylcarbamoyl-2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one which was purified by distillation at 131°-135°C and 0.3mm pressure. The colourless oil gave the following elemental analysis by weight:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Using the same procedure as described in Example 4, 17 parts of 2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one and 14.3 parts of p-tolyl isocyanate were reacted together and afforded a solid material which was recrystallised from petroleum ether (of boiling range 60° to 80°C) to yield 21 parts of 4-p-tolylcarbamoyl-2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one of melting point 126°C. This material gave the following elemental analysis by weight: were reacted together afforded a solid material which was recrystallised from petroleum ether (of boiling range 60° to 80°C)

Procedure: Using the same procedure as described in Example 4, 17 parts of 2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one and 32 parts of n-octadecyl isocyanate were reacted together and afforded 4-n-octadecylcarbamoyl-2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one as a colourless solid which was recrystallised from petroleum ether (of boiling range 60° to 80°C) and had a melting point of 56.5°-58°C. This material gave the following elemental analysis by weight: were reacted together

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Using conditions similar to Example 4, 17 parts of 2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one and 17 parts of p-chlorophenylisocyanate afforded 20 parts of 4-p-chlorophenylcarbamoyl-2,2,7,7-tetramethyl-1,4-diazacycloheptan-5-one as a colourless solid of melting point 119° -121°C. This material had the following elemental analysis by weight:
