The vessel tendered NOR on 6 June but had to wait at anchorage until 20 June, arriving at berth that day and being granted free pratique. The owner’s reliance on The Delian Spiritalso failed here because, despite the fact that the crew were indisputably healthy when the NOR was tendered on 6 June, there was an express requirement that she be in free pratique. The same argument failed in London Arbitration 1/00. A Reaxys search (June 2013) for R-CO- N-R′(Boc), both R and R′ any group except hydrogen, corrected for R-N(Boc) 2 below that are obviously included, gave 7800 − 5600 = 2200 hits.b) S. Bhatia, S.

Other charterparty clauses take a different approach and may make having free pratique a condition precedent to the tendering of a NOR. In that case, whether obtaining free pratique is irrelevant as the clause requires it to have been actually granted. In those circumstances, the owners bear the risk of delays in obtaining free pratique, even if the crew might be completely healthy. Boc 2N-compounds were originally prepared from urethanes with Boc 2O/ DMAP. 13 For amine synthesis from halides alkylation of Boc 2NH is rather convenient. Similarly, alkylation of Cbz(Boc)NH provided a product of type Cbz(Boc)N-R. 34 Reacting an easily obtained Cbz-protected spermidine substrate with Boc 2O/ DMAP ultimately provided N 8-Boc- N 1-Cbz-spermidine via a derivate of this kind, i.e. full discrimination between two primary and one secondary amino functions was accomplished. 35a In the same way Cbz-hydrazine served as a reagent for stepwise alkylation/ acylation of hydrazine. 35b,c Also chiral products of these and related types have been obtained in the presence of a proper ligand. 36 The Boc 2O/DMAP reagent has a considerable scope. Boc-substituents have also been introduced in this way on oxygen, sulphur as well as carbon atoms but so far mainly N-Boc-substitution has been explored preparatively. Notes and references

Up to now relatively few compounds of this type have been made. 42 5 Scope of the Boc 2O/DMAP reagent Due to its excellent reactivity and specificity Boc 2O is a superb reagent for the synthesis of derivatives of amines. Addition of the powerful nucleophilic catalyst DMAP highly increases its reactivity and is accompanied by decreases in selectivity.

Soc., Perkin Trans. 1, 1988, 1905–1911 RSC; By having that ability to tender the NOR, laytime starts running earlier without the vessel having to wait what might otherwise be a lengthy period. That ensures that the vessel and her owners do not bear the risk of delays at the port, unconnected with the health of the crew or the history of trading. Parties, of course, remain free to decide themselves when, in the context of free pratique, the NOR can be tendered. Some forms say nothing about free pratique – Gencon 1976 and ASBATANKVOY 1977 being two examples. As a result, the common law applies. L. Grehn, K. Gunnarsson and U. Ragnarsson, Acta Chem.

An early attempt to react acetanilide with dimethyl dicarbonate in the presence of DMAP was unsuccessful 13 but with 4-thiazolidinone as substrate a methyloxycarbonyl derivative was obtained, although in lower yield than with Boc 2O. 23 The latter substrate with Cbz 2O/ DMAP also afforded the corresponding Cbz-protected product. 23 Of other analogous reagents investigated only di-1-adamantyl dicarbonate with DMAP was preparatively useful. 47 It has always been the case that a vessel needs to be legally ready to load or discharge the cargo on board, the health of the crew being one of the requirements to meet that legal readiness. It became recognised that, if the crew were healthy, confirming this would be a ‘mere formality’ and as such should not prevent the running of laytime. A Reaxys search (June 2013) for R-N(Boc) 2, R any group except hydrogen, gave 5630 hits and for R-NCbz(Boc) 230 hits. This article first appeared in Maritime Risk International, December 2022. Free pratique is permission given by a port for a vessel to enter once it has been certified free of infectious disease by the competent health authorities. It is required for the vessel to be determined legally ready to load or discharge the cargo, thereby allowing the tender of the vessel’s Notice of Readiness (NOR) and is thus important for the calculation of laytime and demurrage.
